Two Waves Of Same Amplitude Superpose The Resultant Intensity Is Physics QuestionTwo Waves Of Same Amplitude Superpose The Resultant Intensity Is Physics Question

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
