Two waves of same amplitude superpose. The resultant intensity is I₁

Two waves of same amplitude superpose. The resultant intensity is I₁ when they are coherent and I₂ when they are non-coherent. The ratio of I₁ and I₂ will be

Options

(a) (1:1)
(b) (2:1)
(c) (4:1)
(d) (1:4)

Correct Answer:

(2:1)

Explanation:

I₁ = 4I and I₂ = 2I
Therefore, I₁ / I₂ = 4I / 2I = 2 / 1
