Two waves $y_{1} = A_{1} sin (ω t - β_{1})$ and $y_{2} = A_{2} sin (ω t - β_{2})$ superimpose to form a resultant wave whose amplitude is

Options:

Answer:

Solution:

Amplitudes $A_{1}$ and $A_{2}$ are added as vectors. Angle between the two vectors is the phase difference $(β_{1} - β_{2})$ between them. $∴$ Resultant wave, $R = A_{1}^{2} + A_{2}^{2} + 2 A_{1} A_{2} cos (β_{1} - β_{2})$
