Two coherent sources whose intensity ratio is 25:1 produce interferenc

1.	Two coherent sources whose intensity ratio is 25:1 produce interference fringes. Calculatethe ratio of amplitudes of light waves coming from them
Answer» ✡ 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
