Assertion : The fringe closest on either side of the central white fringe in case of interference pattern due to white light is red and the farthest appears blue. Reason : The interference patterns due to different component colours of white light overlap.

The intensity of interference waves in an interference pattern is same as I_(0) . The resultant intensity at any point of observation will be

The intensity of central fringe in the interference pattern produced by two indetical slits is I. When one of the slits is closed then the intensity at the same points is I_(0) . The relation between I and I_(0) is

The central fringe of the interference pattern produced by the light of wavelength 6000 Å is found to shift to the position of 4th dark fringe after a glass sheet of refractive index 1.5 is introduced. The thickness of glass sheet would be

Answer the following: (a) If one of two identical slits producing interference in Young's experiment is covered with glass so that the light intensity passing through it is reduced to 50%, find the ratio of the maximum and minimum intensity of the fringe in the interference pattern. (b) What kind of fringes do you expect to observe if white light is used instead of monochromatic light ?

Two mirror M_(1) and M_(2) make an angle phi with line AB . A point source S is kept at a distance r from the point of intersection of mirror. A small hemispherical annular mask is kept close to S so that no ray emanting from S directly reaches the screen kept at a distance b from the source. Interference pattern of rays reflected from M_(1) and M_(2) is oberved on the screen. Find the fringe width of this interference pattern lambda= wavelength of light being emitted by source.

A : For best contrast between maxima and minima in the interference pattern of Young.s double slit experiment, the intensity of light emerging out of the two slits should be equa. R : The intensity of interference pattern is proportional to square of amplitude.

A : In interference, the fringe obtained at the centre of the screen is known as zeroth order fringe, or the central fringe R : In interference, path difference between the waves from S_(1)" and "S_(2) , reaching the central fringe (or zero order fringe) is zero

Two incoherent sources of light each with equal intensity I_(0) interfere in a medium . Will any interference pattern be observed ? If no, then why ? Also what would be resultant intensity then ?
