\[\Huge{\color{blue}{\text{What is a longitudinal wave-- }}}\] 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|

oh, i did see it.
so it was'nt so good
\[\Huge{\color{red}{nice !!!}}\] Mujhe bhi mere bhai ne LaTeX sikhaya hai @mayankdevnani :)
i didn't say that.
coz medal @hartnn :)
?
He needs medal
lol! :P really ?
yaa !
hey!!!
why do he need medal, he alreadt has one.
*already
i gave him
@hartnn i take medal with you plz can you you are so briallant person plz
it makes no difference if i give you medal or not!
no plz @hartnn
@hartnn bade jiddi ho :)
i am done here.
May be @mayankdevnani u r T_T
  • hba
@hartnn Good Going-Like A Boss :D
@hartnn give me medal sir
so @hba you also
are bhai \(GOKU\) dede
come on you can lol:) @hartnn
why u so desparate for medal ? will it change anything ? will it increase your smartscore ? NO
ok so what is going give me medal...
as your one medal will change my smartscore..!!!
no it won't u don't know about smartscore much, do you ?
no
@hba sir where are you>?
  • hba
I am busy,will check this out later
ok
\[\Huge{\color{red}{\mathbb{So Nice.}}}\]
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
no..it's only about the basic concept of longitudinal waves ok @Miyuru
thnx...

Great !
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.

no you are wrong... i swear @Callisto
@thivitaa @sydneyyy have a look:)
@mayankdevnani pls dont tag these many people like this
any reason?
i have no problem for this tagging :)
@hartnn your a boss
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
@AravindG for your kind inf. friend i don't post this tutorial...i swear...
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.
and also can you copy this line or statement
right @april115 that's my first tutorial and you are just point my mistakes...thats not good...
dont fight frnds
@rahul_rajawat its not fighting.....
@mayankdevnani take it as positive criticism friend
ok.... i respect your feelings
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?
i told u ur presntation was nic ...
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
thnx..for your advice @heena
anytime bro and really u did ur best in dis i must say :)
ok sry @april115
ok i must try best in future @heena
i knw u ll no doubt :)
yaa
No medal, sorry.
ok....mention not!!!
@ash2326 @Aperogalics have a look:)
@mayankdevnani answer my simple question instantly you will get medal on longitudnal waves:)
i don't know...
its depend on you...sir
it is simple one light is a longitudnal wave or not??
no,its a transverse wave...
right?? @Aperogalics
right but does transverse wave need a medium to propagate but light doesn't ????????? what about that?????:)
hmmmm
its a elecrtomagnetic waves
so y u say it is transverse wave??????????
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.
@ash2326 i swear i did'nt cheat
i have a proof... @Callisto @ash2326 @AravindG
@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????????
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.
so u want to say light behaves like wave so it must obey the property of wave then why not???????
ok..sry... i am wrong...can you give me some advise by answering this answer
@mayankdevnani first of all you i m just having fun with you..don't take tension:)
yes light have dual nature but it is not linked with it:)
i have a proof that i am not cheated with any website....
vary nice but im not rely insterrested in this stuff but you did a great job any how
thnx...its my 1 tutorial @mikala1
@calculusfunctions plz don't fun of me..i say it first...
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?
i don't know that Callisto said that
@mayankdevnani you should be writing lessons for people who need the help, not to simply get medals.
Is Callisto right? I don't think you would do anything like that. Would you?
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
no callsito is absolutely wrong... yaa you are right.....
callisto said he copied from website, but he proved that he copied from a book.
yaa..by writing a small note on longitudinal waves @hartnn
Whether it's small or not, as a teacher I cannot condone such behaviour.
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....
can anyone tell me what is meant by writing a TUTORIAL on OS?
yaa you are right @hartnn next time i did'nt do any mistake like this
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.
ok...no problem
you tell me that;s my medal
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
you give me a medal in favour of giving some tips...thnx @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.
well @mayankdevnani post more stuff but making it point by point so people just read it instead of searching google etc. starting is good:)
thnxx
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.
thnx... for your kind information @Callisto
