Question

As shown in arrangement waves with identical wavelengths and amplitudes and that are initially in phase travel through different media, Ray 1 travels through air and Ray 2 through a transparent medium for equal length L, in four different situations. In each situation the two rays reach a common point on the screen.The number of wavelength in length L is N₂ for Ray and N₁ for Ray 1. In the following table, values light at the common point in descending order is :

Accepted Answer

Path difference &#5123;x1 = , &#5123;x2 = &#955;, &#5123;xs = , &#5123;x4 = Therefore I2 > I3 = I4 > I1.
