I have to draw a sine wave that has:

Wavelength = 4
Amplitude = 6

Then Wave 2 is :
Wavelength = 8
Amplitude = 6

I got the first one but then I got stuck on how to draw Wave2.

Also, what is hte superposition of this wave?

the second one is just double wavelength, same amplitude and the superposition is just the sum of the individual displacements at that point where the 2 waves pass each other

If you have the first one, just double the wavelength for the second one, i.e. the first wave goes through 0, 2, 4, therefore the second should go through 0, 4, 8.

Superposition is just adding the waves together.

Kind of like:



The blue wave is a result of superimposing the first and the second waves.


Hope this helps :)
