Question

Two coherent sources whose intensity ratio is 25:1 produce interference fringes. Calculate

the ratio of amplitudes of light waves coming from them

​

Answer 1

✡ Answer ✡

✡ Concept ✡

Intensity of light is directly proportional to its amplitude.

I ∝$A^{2}$

✡ Process ✡

It is given that the intensity is in  the ratio 25:1. So, by using the above concept, we can say that amplitude will be square root of the intensity.

$\frac{I_1}{I_2} =\frac{25}{1}$

$\frac{A_1^{2} }{A_2^{2} } =\frac{25}{1}$

$\frac{A_1}{A_2} =\frac{5}{1}$

So, the amplitudes will be in the ratio 5:1
