The distance between two consecutive bright bands in biprism experiment is 0.32 mm, when red light of wavelength `6400 overset (@)(A)` is used. By how much will this distance change if blue light of wavelength `4800 overset (@)(A)` is used with the same setting?

The distance between two consecutive dark bands in a Young's experiment is 0.32 mm when red light of wavelength 6400 overset (@)(A) is used . By how much will this distance change if yellow light of wavelength 5900 overset (@)(A) is used with the same setting .

The distance between two consecutive bright fringes in a biprism experiement using light of wavelength 6000 overset@A is 0.32 mm, by how much will the distance change, if light of wavelength 4800 overset@A is used.

The fringe separation in a biprism is 3.2 xx 10^-4 m when red light of wavelength 6.4 xx 10^-7 m is used, by how much will this change, if blue light of wavelength 4 xx 10^-7 m is used with the same setting.

In biprism experiment the distance between 4th and 13th bright fringes on same side is measured when light of wavelength 6000 overset (@)(A) is used.On replacing the source of light by another of different wavelength without disturbing the adjustment of the apparatus, it is found that the distance between the 5th and 15th bright fringe on same side is the same as distance measured before. What is the wavelength of light used?

In a biprism experiment, red light of wavelength 6500 overset@A was used. It was then replaced by green light of wavelength 5200 overset@A . Find the value of n for which (n + 1)^th green bright band would coincide with the nth bright band, for the same setting.

What is the minimum distance between two objects which can be resolved by a microscope having the visual angle of 30^@ when light of wavelength 500 nm is used ?

In a biprism experiment, a source of light has a wavelength of 5500 overset@A . Calculate the change in fringe width, if the screen is at a distance of 1 m from the points which are 1mm apart.

In Young's expriment, interference bands are produced on the screen placed at 1.5 m from the two slits 0.15 mm apart and illuminated by a light of wavelength 6500 overset (@)(A) . Find a) the fringe width and b) the change in the fringe width if the screen is taken away from the slit by 50 cm.
