In Young's double slit experiment, light of green, yellow and orange colours are successively used. Write the fringe widths for the three colours in increasing order.

In Young's double slit experiment what is the shape of interference fringes?

In Young's double slit experiment,the sepaation between the slit is halved and distance between the slits and screen is doubled.The fringe width is

In Young's double slit experiment,light of wavelength 5,000 overset @A is used.The screen on which fringes are projected is 1.5 m from the centre of the narrow slits. The third bright band on the screen is formed at a distance of 1 cm from the central bright band calculate the separation between the slits.

In a Young's double slit experiment ,the distance between the slits and the screen is 1 m.If the distance between the slits is 5 mm,the fringe width is found to be 0.1 mm.Calculate the wavelength of the light used.
