PhysicsEasysingle choice

Two sinusoidal waves of intensity $I$ having same frequency and same amplitude interferes constructively at a point. The resultant intensity at a point will be

Options:

Answer:

Solution:

The resultant intensity is given by $I_{R} = I_{1} + I_{2} + 21 cos ϕ$ For constructive interference, $cos ϕ = 1$ $∴ I_{R} = I_{1} + I_{2} + 212$ or $I_{R} = 4 I$ (Given $I_{1} = I_{2} = I)$
