two coherent sources whose intensity ratio is 25:1 produce interferenc – InterviewSolution

1.

two coherent sources whose intensity ratio is 25:1 produce interference fringes . calculate the ratio of amplitude of light waves coming from them.

Answer»

5:1

Explanation:

As, I $\alpha$ $A^{2}$

Given : $I_{1} : I_{2} = 25 : 1$

so A1 / A2 = Square root of (I1 / I2)

so Square root of 25 & 1 is 5 ,1 res[ectively

hence the answer to this question is 5:1
