Question

n identical waves each of intensity I₀ interfere with each other. The ratio of maximum intensities if the interference is (i) coherent and (ii) incoherent is ______.

Options

• n²

• `1/"n"`

• `1/"n"^2`

• n

Answer 1

n identical waves each of intensity I₀ interfere with each other. The ratio of maximum intensities if the interference is (i) coherent and (ii) incoherent is n.

Explanation:

`(("Maximum intensity")  "coherent interference")/ (("Maximum intensity")" in coherent interference")`

= `("n"^2"I"_0)/"nI"_0`

= n
