PhysicsEasysingle choice

Two identical light waves having phase difference $ϕ$ propagate in the same direction. When they superpose, the intensity of the resultant wave is proportional to

Options:

Answer:

Solution:

For two identical light waves

$I_{R} = 4 I \cos^{2} \frac{ϕ}{2}$

$∴ I_{R} \propto \cos^{2} \frac{ϕ}{2}$
