Which part of the wave is changed when there is interference? a. the amplitude b. the crest c. the trough d. the wavelength

A). The amplitude

Explanation:

When two or more coherent waves superimpose then the resultant wave is given as

here the intensity of resultant wave is different from the intensity of the individual waves.

This phenomenon is known as interference

As we know that intensity of wave is directly depends on the square of the amplitude of the wave

So here we can say that after interference the intensity of the wave will change.

So correct answer is

A). The amplitude
