Since.... 1 Node = 1 Loop = λ/2 2 Node = 2 Loops = λ If one Node = 0.40m two Nodes = 0.80m Therefore the 2 Nodes = Wavelength = 0.80m, the wavelength is 0.80m To Figure out the wavelength, we're going to use..........V = f X λ Rearrange the formula so that we're solving for "λ" λ = V/f λ = 6m/sec /0.80m λ = 7.5 or 8Hz Therefore the Frequency is 8Hz

@dan815 dear can you please help me????????????????
YumYum247
  • YumYum247
please check my work :)
YumYum247
  • YumYum247
the important question here i wanna ask you is that, does the length of 2 Nods equals the wavelength?!?!?!?!?
dan815
  • dan815
Frequency is number of cycles per second or in other words the number of wavelengths per second if the the wavelength is 0.8m and the wave is moving at 6m/s how many wave lengths did it move in 1 second? that is 6/0.8 so the frequency is 6/0.8 cyclces/sec or 6/0.8 hz= 6/8/10 = 60/8 = 15/2 Hz
YumYum247
  • YumYum247
dear 0.8m is not the wavelength, that's just my calculations....The question says the difference between two Nodes is 0.40m. Since 2 Loops = 1wavelength, that should also mean that 2 nodes equal 2 loops = wavelength....am i right?!?!?!?
YumYum247
  • YumYum247
therefore the distance between two nodes equals to 1 wavelength.
YumYum247
  • YumYum247
am i right?!?!?!?
dan815
  • dan815
why dont you ask ASTROphysics your first choice
dan815
  • dan815
hmmph :@
YumYum247
  • YumYum247
cuz i remember wavelength could be any distance between two success crests or trough or the the distance between them on the equilibrim....

he's back!!! Yay :"D

@Astrophysics Please help!!!

lol im jk, 0.8 is probably right

did u hear that astro

sorry people my internet is being internet here -_-

\[v = \lambda f \implies f = \frac{ v }{ \lambda } = \frac{ 6 m/s }{ 0.8m } = 7.5Hz\]

that's what i got!!!

That looks good

What you think danni boi

  • YumYum247
but do you agree with what i said earlier?!?!?!
YumYum247
  • YumYum247
The question says the difference between two Nodes is 0.40m. Since 2 Loops = 1wavelength, that should also mean that 2 nodes equal 2 loops = wavelength....am i right?!?!?!?
dan815
  • dan815
i can show u a proof for it
Astrophysics
  • Astrophysics
Yeah, good :)
YumYum247
  • YumYum247
ok so the distance between two nodes (0.40m + 0.40m) equals to 1 wavelength = 0.8m
Astrophysics

YumYum247
  • YumYum247
yes does that equal to the distance of 1 wavelength?!?!?!?!
YumYum247
  • YumYum247
since1 Node = 1 Loop = λ/2 2 Node = 2 Loops = λ If one Node = 0.40m two Nodes = 0.80m Therefore the 2 Nodes = Wavelength = 0.80m, the wavelength is 0.80m
Astrophysics
  • Astrophysics
Yes, 2 nodes will make a wavelength we can see this in your calculation as well notice 1 node gives \[1~ node = \frac{ \lambda }{ 2 }\] so 2 will give lambda :)
Astrophysics
  • Astrophysics
So 1 node is half a wavelength
Astrophysics
  • Astrophysics
Don't doubt yourself! You're thinking right, but you need to also compare the concepts to the math and see if it makes sense, :)
