Question

This image represents a wave.



What would a wave look like if it had less amplitude but the same wavelength?

Answer 5

Less amplitude means the wave in the answer will need to be less than 5 units high at its highest point, also note that the wave in the question is a sine wave not a sawtooth as in A and C.
B has a wavelength of 6, and D has a wavelength of 10, so for the wavelength (number of units from one point on a wave to the corresponding point on the next wave train) to remain the same, 6, the answer must be B

Answer 6

thank you very much @Silent_Sorrow
