In double-slit experiment using light of wavelength 600 nm, the angular width of a fringe formed on a distant screen is `0.1^@`. What is the spacing between the two slits ?

In Young's double-slit experiment using monochromatic light of wavelength lambda , the intensity of light at a point on the screen where path difference is lambda is K units. What is the intensity of light at a point where path difference is lambda/3 ?

In a biprism experiement, the slit is illuminated by light of wavelength 4800 overset@A . The distance from the slit to the screen is 1 metre. If the distance between the two virtual sources is 0.3 cm, determine the distance between the 5th bright band on one side and 5th dark band on the other side.

A parallel beam of green light of wavelength 546 nm passes through a slit of width 0.4 mm. The intensity pattern of the transmitted light is seen on a screen which is 40 cm away. What is the distance between the two first order of minima?

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 a double -slit arrangement the slits are separated by a distance equal to 100 times the wavelength of the light passing through the slits. What is the distance between these maxima on a screen 50.0 cm from the slits ?
