Light rays emerge from denser medium (`n_2`), refract from curved surface and then travel through rarer medium (`n_1`), formula for this is ….........

A

`-(n_2)/(u)+(n_1)/(v)=(n_1-n_2)/(R)`

B

`-(n_2)/(u)+(n_1)/(v)=(n_2-n_1)/(R)`

C

`-(n_1)/(u)+(n_2)/(v)=(n_2-n_1)/(R)`

D

`-(n_1)/(u)+(n_2)/(v)=(n_1-n_2)/(R)`

Text Solution

In YDSE shown in figure a parallel beam of light is incident on the slits from a medium of refractive index n_(1) . The wavelength of light in this medium is lambda_(1) . A transparent of thickness t and refractive index n_(3) is put in front of one slit. The medium between the screen and the plane of the slits is n_(2) . The phase difference between the light waves reaching point O (symmetrical, relative to the slits) is

As shown in figure waves with identical wavelengths and amplitudes and which are intially in phase travel through difference media. Ray 1 travels through air and Ray 2 through a transparent medium for equal length L, in four different situations. Rays reach a common point on the screen. The number of wavelengths in length L is N_(2) for Ray 2 and N_(1) for Ray 1. In the following table, values of N_(1) and N_(2) are given for all four situations. The order or the situations according to the intensity of the light at the common point in descending order is Situations 1 2 3 4 N_(1) 2.75 1.80 3.00 3.25 N_(2) 2.75 2.80 3.25 4.00
