Question

when two identical waves superpose, what changes A-Wavelength B-velocity C amplitude D-frequency
​

Answer 1

C. Amplitude

Resultant Amplitude, Ar = $\sqrt{a {2} + a {2}}$

Where, a is amplitude of those identical waves, but the magnitude depends on superposition method also like constructive or destructive. For constructive, amplitudes will be added and subtracted for destructive.

hope this will help you
