The contrast in the fringes in any inter...

The contrast in the fringes in any interference pattern depends on -

A

fringe width

B

wavelength

C

intensity ratio of the sources

D

distance between the source

Text Solution

Verified by Experts

The correct Answer is:
C
contrast indicates the ratio of maximum possible intensity on screen to the minima possible intensity.
As `(I_(max))/(I_(min))=(sqrt(I_(1))+sqrt(I_(2)))^(2)/((sqrt(I_(1))-sqrt(I_(2)))^(2))`
So it only depends on the source intensity

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 ?
