The intensity of light coming from one of the slits in Young's experiment is twice the intensity of light coming from the other slit. What will be the approximate ratio of the intensities of the bright and dark fringes in the resulting interference pattern?

Polarods are used to control the intensity of light coming through windows of

If I is the intensity of light entering into the optical fibre and I_(e) is that emerging from the fibre then

Two slits in Young Experiment have width in the ratio 81:1 . What is the ratio of the amplitudes of the waves coming from them.

In Young's double slit experiment , a thin uniform sheet of glass is kept in front of two slits , parallel to the screen having slits . The resulting interference pattern will satisfy

The maximum intensity in Young’s double slit experiment is I_0 .Distance between the slits is d=2lambda ,where lambda is the wavelength of monochromatic light used in experiment. What will be the intensity of light in front of one of the slits on a screen at a distance D = 6 d?

How does the width of dark fringe in interference pattern vary from that of the bright fringe ?

In Young's double-slit experiment using monochromatic light of wavelength lambda , the intensity of light at a point on the screen where path difference is lambda is K units. What is the intensity of light at a point where path difference is lambda/3 ?

In Young's experiment, the distance between two slits is 0.8mm and the distance of the screen from the slit is1.2 m. If the fringe width is 0.79 mm, the wavelength of light used is

In a biprism experiment, the width of fringe is 0.12 mm when the eyepiece is at a distance of 100 cm from the slit. What would be the width of the fringe if the eyepiece is moved towards the slit by 25 cm ?
