Interference is produced with two coherrent sources of same intensity. If one of the source is covered with a thin film so as to reduce the intensity of light coming out of it to half,

Bright fringes will be less bright and dark fringes will be less dark

B

Bright fringes will be more bright and the dark fringes will be more dark

C

Brightness of both types of the fringes will be same (General illumination)

The light waves from two coherrent sources of same intensity I interfere. At the minimum, the intensity of light is zero. What is the intensity of light at the maximum ?

Interference fringes are obtained using two coherent sources whose intensities are in the ratio 4 : 1. Then the ratio of the intensities of the bright and dark bands is

(a) When monochromatic light is incident on a surface separating two media, the reflected and refracted light both have the same frequency as the incident frequency. Explain why? (b) When light travels from a rarer to a denser medium, the speed decreases. Does the reduction in speed imply a reduction in the energy carried by the light wave? (c) In the wave picture of light, intensity of light is determined by the square of the amplitude of the wave. What determines the intensity of light in the photon picture of light

For best contrast between maxima and minima in the interference pattern of Youngs double slit experiment, the intensity of light emerging out of the two slits should be :

In an interference exeperiment, third bright fringe is obtained at a point on the screen with a light of 700 nm. What should be the wavelength of the light source in order to obtain 5th bright fringe at the same point?

In Young.s double slit experiment the source is white light. One slit is covered with red filter and the other with blue filter. There shall be
