Two coherent plane waves of identical frequency, polarization and intensity interfere at a point where they differ in phase by . What is the resulting intensity?
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Given: Phase between two coherent plane wave ϕ=60°. The resultant intensity of two coherent waves is given as, IR=I1+I2+2I1I2cosϕ, where I1 and I2 are the intensity of two coherent waves, and ϕ is the phase angle. Since the intensity of both waves are…
