$\Huge{\color{blue}{\text{What is a longitudinal wave-- }}}$ A wave in which the particles of the medium oscillate(vibrate) to and fro about their mean position in the direction of propagation of the wave is called a LONGITUDINAL WAVE.. |dw:1352632732132:dw| Longitudinal waves can be produced in any medium .viz.in solids,liquids and in gases. $\Large{\color{red}{\text{Graphical representation of longitudinal wave --- }}}$ Longitudinal wave is represented by density-distance graph.In figure , the horizontal line OX represents the normal density of air.All the points above this line represent greater density.In a compression of a longitudinal wave ,the density of the particles is the high.So, here A and C represent compressions.All the points below the line OX represent less density(than normal).In a rarefraction,the density of the particles is less than in the normal. So, here B and D represent rarefractions. |dw:1352633328762:dw|

45. Miyuru

HI The tutorial is good. What about Electromagnetic waves ?????? :D Are u really posting tutorials too get medals This is not a good idea for getting medals @mayankdevnani Anyway here is my medal. It won't increase your Smartscore neither..:D

46. mayankdevnani

no..it's only about the basic concept of longitudinal waves ok @Miyuru

47. mayankdevnani

thnx...

@mayankdevnani pls dont tag these many people like this

58. mayankdevnani

any reason?

59. rahul_rajawat

i have no problem for this tagging :)

60. april115

@hartnn your a boss

61. AravindG

i think posting the tutorial and @ mentioning a few people who u truly think would be intrstd in it is better ...@jitesh said this behaviour makes us feel u running after medals ...anyways the tutorial is nice friend ..loved the way of presentation

62. mayankdevnani

@AravindG for your kind inf. friend i don't post this tutorial...i swear...

63. april115

that is true but at the end end he's here asking for help but so desperate for us to give him medals he should be happy ppl are helping him.

64. mayankdevnani

and also can you copy this line or statement

65. mayankdevnani

right @april115 that's my first tutorial and you are just point my mistakes...thats not good...

66. rahul_rajawat

dont fight frnds

67. mayankdevnani

@rahul_rajawat its not fighting.....

68. AravindG

@mayankdevnani take it as positive criticism friend

69. mayankdevnani

ok.... i respect your feelings

70. heena

mayank u knw if we ur frnd will not point out ur mistakes den later on u ll go on wid di mitake and unable to improve urself so u decide u want to improve or not?

71. AravindG

i told u ur presntation was nic ...

72. april115

well im so sorry. but you know what i speak the truth and what i wrote was on my mind so i dnt care if i pointed out mistakes if you want to make a good impression on getting fans you dnt desperately ask them for medals

73. mayankdevnani

thnx..for your advice @heena

74. heena

anytime bro and really u did ur best in dis i must say :)

75. mayankdevnani

ok sry @april115

ok....mention not!!!

84. AravindG

lols @geerky42

85. mayankdevnani

@ash2326 @Aperogalics have a look:)

86. Aperogalics

@mayankdevnani answer my simple question instantly you will get medal on longitudnal waves:)

87. mayankdevnani

i don't know...

88. mayankdevnani

its depend on you...sir

89. Aperogalics

it is simple one light is a longitudnal wave or not??

90. mayankdevnani

no,its a transverse wave...

91. mayankdevnani

right?? @Aperogalics

92. Aperogalics

right but does transverse wave need a medium to propagate but light doesn't ????????? what about that?????:)

93. mayankdevnani

hmmmm

94. mayankdevnani

its a elecrtomagnetic waves

95. Aperogalics

so y u say it is transverse wave??????????

96. mayankdevnani

Light isn't actually a wave it just behaves similar to a wave. It is actually part of the electromagnetic spectrum and it has different properties.

97. mayankdevnani

@ash2326 i swear i did'nt cheat

98. mayankdevnani

i have a proof... @Callisto @ash2326 @AravindG

99. Aperogalics

@mayankdevnani so you want to say light is not a transverse wave or u want to say that EM wave is a broader term which exhibit some property of transverse????????

100. mayankdevnani

Light isn't actually a wave it just behaves similar to a wave. It is actually part of the electromagnetic spectrum and it has different properties.

101. Aperogalics

so u want to say light behaves like wave so it must obey the property of wave then why not???????

102. mayankdevnani

ok..sry... i am wrong...can you give me some advise by answering this answer

103. Aperogalics

@mayankdevnani first of all you i m just having fun with you..don't take tension:)

104. Aperogalics

yes light have dual nature but it is not linked with it:)

105. mayankdevnani

thnx.. @Aperogalics

106. mayankdevnani

i have a proof that i am not cheated with any website....

107. mayankdevnani

ok @Callisto @AravindG

108. mayankdevnani

@mikala1 @KatherinePierce1864 @zigzagoon2000 have a look:)

109. mayankdevnani

@calculusfunctions @LonelyandForgotten @lundaaaaa @JerJason

110. mikala1

vary nice but im not rely insterrested in this stuff but you did a great job any how

111. mayankdevnani

thnx...its my 1 tutorial @mikala1

112. mayankdevnani

@calculusfunctions plz don't fun of me..i say it first...

113. calculusfunctions

Yes? Why are you calling everyone over @mayankdevnani ? I know that it's a tutorial but I already know this stuff. LOL Why would I make fun of you. I haven't read all of it, I just glanced through it. Do you want me to read it? If I do then I have to give you my honest opinion. Also why is Callisto saying that you copied from a book?

114. mayankdevnani

i don't know that Callisto said that

115. calculusfunctions

@mayankdevnani you should be writing lessons for people who need the help, not to simply get medals.

116. calculusfunctions

Is Callisto right? I don't think you would do anything like that. Would you?

117. mayankdevnani

ok i don't know the mean of tutorial...first one ...in maths section i first written the tutorial on the topic of slope intercept and i copied it from the net and one moderator come and suspend me for 1 hour ...but this time i am not copied from net...i swear that's why i need medals....thanks for your advice @calculusfunctions

118. mayankdevnani

no callsito is absolutely wrong... yaa you are right.....

119. hartnn

callisto said he copied from website, but he proved that he copied from a book.

120. mayankdevnani

yaa..by writing a small note on longitudinal waves @hartnn

121. calculusfunctions

Whether it's small or not, as a teacher I cannot condone such behaviour.

122. hartnn

you did not write in your own words on what you understood from the book. you copied each and every word from that ! now thats copying....

123. mayankdevnani

can anyone tell me what is meant by writing a TUTORIAL on OS?

124. mayankdevnani

yaa you are right @hartnn next time i did'nt do any mistake like this

125. calculusfunctions

The problem I have with this, as a teacher is that there are kids like @mikala1 who I know is viewing this, come on line to genuinely learn. When you copy and plagiarize, that sets a bad example for them. I hope @mikala1 and any other student viewing this, you know that plagiarizing and cheating are wrong. @mayankdevnani for this reason you will not be receiving any medals from me.

126. mayankdevnani

ok...no problem

127. mayankdevnani

you tell me that;s my medal

128. mikala1

Ooo i have seen it a million times its ok i dont really use these things i just need help well i should say havent gotten in to longtude yet sooo... at least ik this is out of a book and not wrong but it is wrong what happend thanks

129. mayankdevnani

you give me a medal in favour of giving some tips...thnx @calculusfunctions

130. calculusfunctions

That's OK @mayankdevnani we're all human beings and we learn from mistakes. Let's just forget it happened and move on with the hopes that it never happens again. All is forgiven.

131. mayankdevnani

thnx... @calculusfunctions

132. Aperogalics

well @mayankdevnani post more stuff but making it point by point so people just read it instead of searching google etc. starting is good:)

133. mayankdevnani

thnxx

134. Callisto

Well, my comment is actually ''I suspect if this is another plagiarism from the book Living Science Physics 9 by Dhiren M Joshi, the chapter of Longitudinal Waves on page 173 to page 174.''. The link is just a proof. Copying a hardcopy book or softcopy one is also plagiarism. Without proper acknowledgement to the writer and claiming it as your tutorial is not an acceptable.

135. mayankdevnani

thnx... for your kind information @Callisto
