Question

Can someone please check my 6-11? More especially 6 & 8.

Answer 1

@kewlgeek555 can you ?

Answer 2

@RatzLover95 @thomaster @AshiKothari

Answer 3

6 - looks like they may have same amplitude. The have different frequency and wavelength.
7 - OK
8 Looks like they have the same frequency. The have different amplitude
9 - OK
10 - since f is the same then 'pitch' is the same
11 - looks like wavlenght is all the same.

Just my estiamtes from the drawings...

Answer 4

@MrNood could 8 be pitches ?

Answer 5

pitch is just a less technical term for frequency.
The drawing shows them all with same frequency - therefore same pitch

Answer 6

do you think you could open the website at the top of the page and try to figure out how to complete 12-15?

Answer 7

You need to do the 'experiment' first.

There is a simple equation relating
velocity, wavelength and frequency

Find that equation - it will be needed for 12 - 15

Answer 8

speed = wavelength x frequency ?

Answer 9

yes
(btw - I'm out now...)

Answer 10

Number eight is different amplitudes. You can see the wavelength is the same, so you assume the frequency or pitch is the same.

Answer 11

10. The answer should be D) all the same because pitch isn't volume ( volume = amplitude) pitch is the same frequency. Since the wavelength is the same, the pitch will be the same

Answer 12

6. I think it is different wavelengths and frequencies. The amplitudes look about the same, but since the wavelength is different, the frequencies will most likely be different
