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 wavelengths in length L is 
for Ray 2 and 
for Ray 1. In the following table, values of and are given for all four situations, The order of the situations according to the intensity of the light at the common point in descending order is :
The correct answer is:
