Vedclass · Answer

(C) The resultant amplitude $R$ of two coherent waves with amplitudes $a_1$ and $a_2$ and phase difference $\phi$ is given by the formula: $R = \sqrt{a_1^2 + a_2^2 + 2a_1a_2 \cos \phi}$.From this expression,it is clear that the resultant amplitude $R$ depends on both the individual amplitudes $(a_1, a_2)$ and the phase difference $\phi$ between the waves.Therefore,the correct option is $C$.
