Green light of wavelength 5100 Å 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 slit separation .

A monochromatic light of wavelength 5100 Å from a narrow slits is incident on a Young's double-slit in an experiment. The overall separation of 10 fringes on a screen in 2 cm. If the screen is 200 cm away, calculate the slit separation.

Light of wavelength 5000 Å is incident on a double with and the interference fringes are formed on a screen plated at a distance of 1m from the slits. If the distance between the two consecutive dark bands is 1 mm, then the distance between the two slits is

A Lloyd's mirror or length 5 cm is illuminated with mon ochromatic light of wavelength lambda (= 6000 Å) from a narrow 1 mm slit in its plane and 5 cm plane from its near edge. Find the fringe width on a screen 120 cm from the slit and width of interference pattern on the screen.

Light of wavelength 5500 Å falls on a slit on a slit of width 0.13 cm at normal incidence. Calculate the width of the central maximum on a screen kept 2.5 m away from slit.

If two slits is Young's experiment are 0.4 mm apart and fringe width on a screen 200 cm away is 2 mm the wavelength of light illuminating the slits is

In a double slit interference experiment, the fringe width obtained with a light of wavelength 5900 Å was 1.2 mm for parallel narrow slits placed 2 mm apart. In this arrangement. If the slit separation is increased by one-and-half times the previous value, then the fringe width is

A source emitting light of wavelengths 480 nm and 600 nm is used in a double slit interference experiment. The separation between the slits is 0.25 mm and the interference is observed on a screen placed at 150 cm from the slits. Find the linear separation between the first maximum (next to the central maximum) corresponding to the two wavelengths.

White coherent light (400 nm-700 nm) is sent through the slits of a Youngs double slit experiment. The separation between the slits is 05 mm and the screen is 50 cm away from the slits. There is a hole in the screen at a point 1.0 mm away (along the width of the fringes) from the central line. (a) Which wavelength(s) will be absent in the light coming from the hole ? (b) which wavelength(s) will have a strong intensity ?

A light of wavelength 6000Å is incident on a single slit . First minimum is obtained at a distance of 0.4 cm from the centre . If width of the slit is 0.3 mm, the distance between slit and screen will be
