Light of wavelength `lambda = 5890 Å` fall on a double-slit arrangement having separation `d = 0.2 mm`. A thin lens of focal length `f = 1 m` is placed near the slits. The linear separation of fringes on a screen placed in the focal plane of the lens is

In Young's double slit experiment with slit separation d, a monochromatic light of wavelength lamda is used. The angular separation of the fringes is

A plane wavefront (lambda=6xx10^-7m) falls on a slit 0.4m wide. A convex lens of focal length 0.8m placed behind the slit focuses the light on a screen. What is the linear diameter of second maximum?

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 .

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.

A slit of width 0.025 mis placed in front of a lens of focal length 50 cm. The slit is illuminated with light of wavelength 5900 Å. Calculate the distance between the centre and first dark band of diffraction pattern obtained on a screen placed at the focal plane of the lens.

A light of wavelength lambda falls on a narrow slit of width d.A diffraction fringe is formed on a screen placed at distance D from the slit. If the linear width of the central maximum equals to the width of the slit, will be the value of D?
