What are coherent sources ? Green light of wavelength 5100 Å is incident on a double slit. If the overall separation of 10 fringes on a screen 200 cm away from the slits is 2 cm find the distance between the slits.

What are coherent sources? Green light of wavelength 5100 @A is incident on a double slit. IF the overall separation of 10 fingers on a screen 200 cm away from the slits is 2, find the distance between the slits.

Green light of wavelength 5100 A from a narrow slit is incident on a double slit. If the overall separation of 10 fringes on a screen 200 cm away is 2 cm find the separation between the slits.

A parallel light beam of wavelength 6000Å passes through a slit 0.2 mm wide and forms a diffraction pattern on a screen 1.0 m away from the slit. Find the width of the central maximum in mm on the screen.

A light of 5000overset@A is incident on the double slit and a fringe is observed on a screen 2m apart of fringe width 0.16mm. What is the slit width?

Light of wavelength 6500 Å passes through a slit 0.1 cm wide and forms a diffraction pattern on a screen 1.8 m away. The width of the central maximum in mm is

What is the effect on the interence pattern in Young's double slit experiment if (i) screen is moved away from the slits (ii) separation between the slits is increased

To prodce inteference fringes in Young' s double slit experiment light consisting of two wavelengths of 6500 Å and 5200 Å is used. (i) Determine the distance of the third maxima from the central maxima for light of wavelength 6500 Å . (ii) At what minimum distance from the central maxima will the bright points (maxima) for two waves superpose? Given that distance between the two slits is 2 mm and the distance of the screen from the plane of the slits is 120 cm.

A parallel beam of light of wavelength lambda is incident normally on a single slit of width d. Diffraction bands are obtained on a screen placed at a distance D from the slit. The second dark band from the central bright band will be at a distance given by

In Young's double slit experiment, light of wavelength lambda passes through the double-slit and forms interference fringes on a screen 1.2 m away. If the difference between 3rd order maximum and 3rd order minimum is 0.18 cm and the slits are 0.02 cm apart, then lambda is

A single narrow slit of width 0.1 mm, is illuminated with a parallel beam of light of wavelength 600xx10^(-9) m . An diffraction fringe is formed on a screen 40 cm away from the slit. At what distance, will the third minimum band be formed from the central maximum band?
