The ratio of intensity of two waves in the Young's double slits experiment is 25 : 9. The ratio of amplitude of two waves will be respectively:

$\frac{5}{3}$

The correct answer is Option (2) → $\frac{5}{3}$

In young's double slit experiment,

$\frac{I_1}{I_2}=\left(\frac{A_1}{A_2}\right)^2$

I = Intensity

A = Amplitude

$⇒\left(\frac{A_1}{A_2}\right)=\sqrt{\frac{25}{9}}=\frac{5}{3}$
