A double-slit apparatus is used to observe an interference patten projected on a screen from a stationary light source. If the light source is instead moved toward the double slits at constant speed along the axis of symmetry. What will be observed on the screen ?

A

The interference patten will remain unchanged

B

The fringes will move father apart to a new fixed direction.

C

the fringes will move closer together to a new fixed distance.

D

The fringes will continue to move further and farther apart as the source is brought closer.

Statement-1: In Young's double slit experiment the two slits are at distance d apart. Interference pattern is observed on a screen at distance D from the slits. At a poit on the screen when it is directly opposite to one of the slits, a dard fringe is observed then the wavelength of wave is proportional of square of distance of two slits. Statement-2: In Young's double slit experiment, for identical slits, the intensity of a dark fringe is zero.

Describe Young's double slit experiment to produce interference pattern due to a monochromatic source of light. Deduce the expression for the fringe width.

Red light is generally used to observe diffraction pattern from single slit. If blue light is used instead of red light, then diffraction pattern.

A young.s double slit experiment uses a monochromatic source. The shape of interference fringes formed on a screen is

An observer measures speed of light to be C, when he is stationary with respect to the source. If the observer moves with velocity V towards the source then the velocity of light observed will be

A : In Young.s double slit experiment, we observe an interference pattern on the screen if both the slits are illuminated by two bulbs of same power. R : The interference pattern is obserbed only when source are monochromatic.

In young's double slit experiment with monochromic light, fringes are obtained on a screen placed at some distance from the plane of slits. If the screen is moved by 5 cm towards the slits, then the change in fringe width is 30mum if the distance between the slits is 1mm, then calculate wavelength of the light used.

In Young's double-slit experiment, the slit are 0.5 mm apart and the interference is observed on a screen at a distance of 100 cm from the slits, It is found that the ninth bright fringe is at a distance of 7.5 mm from the second dark fringe from the center of the fringe pattern. The wavelength of the light used in nm is

A Young's double slit apparatus has slits separated by 0.25mm and a screen 48cm away from the slits. The whole apparatus is immersed in water and the slits are illuminated by the red light ( lambda=700nm in vacuum.) Find the fringe width of the pattern formed on the screen. (mu_w = 4//3)

If the source of light used in a young's double slit experiment is changed from red to violet
