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.

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 .

In Yonung's double-slit experiment, two slits which are separated by 1.2 mm are illuminated with a monochromatic light of wavelength 6000 Å The interference pattern is observed on a screen placed at a distance of 1 m from the slits. Find the number of bright fringes formed over 1 cm width on the screen.

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.

A single slit of width 0.20 mm is illuminated with light of wavelength 500 nm . The observing screen is placed 80 cm from the slit. The width of the central bright fringe will be

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.

Two slits, 4 mm apart, are illuminated by light of wavelength 6000 Å . What will be the fringe width on a screen placed 2 m from the slits

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
