Monochromatic light of wavelength `5000 overset@A` from a narrow slit is incident on the double slit. If the separation of 10 fringes on the screen 1 m away is 2 cms. Find the slit separation.

Monochrmoatic light of wavelength 500nm from a narrow slit is incident on the double slit. If the separation of 10 fringes on the screen 1m away is 1cms . Find the slit separation.

How does fringe width vary with distance between the double slit and the screen?

Light of wavelength 500 nm is incident on a slit of width 0.1 mm. The width of the central bright line on the screen is 2 mm. The distance of the screen is

In Young's double slit experiment the two slits 0.15mm apart are illuminated by monochromatic light of wavelength 450nm . The screen is 1.0m away from the slits. (a) Find the distance of the second (i) bright fringe, (ii) dark fringe from the central maxima. (b) How will the fringe pattern change if the screen is moved away from the slits ?

A light of wavelength 4000 overset@A forms third bright fringe at some point on the screen in Young’s double slit experiment. Find the wavelength of light which will form second bright fringe at the same point.

A parallel beam of light of wavelength 500nm falls on a narrow slit and resulting diffraction pattern is observed on a screen 1m away. It is observed that the first minimum is at a distance of 2.5 mm from the centre of the screen. Find the width of the slit.

How does fringe width vary with slit separation?

In Young’s double slit experiment, carried out with light of wave length lambda = 5000 overset@A , the distance between the slits is 0.2 mm and the screen is at 200 cm from the slits. The central maximum is at x = 0 . The third maximum (taking central maximum as zeroth maximum) will be at what value of x ?

Two slits 0.3mm apart are illuminated by light of wavelength 4500Å . The screen is placed at 1m distance from the slits. Find the separation between the second bright fringe on both sides of the central maximum. Data : d=0.3mm=0.3xx10^(-3)m , lambda=4500Å=4.5xx10^(-7)m , D=1m , n=2 , 2x=?
