Write difference between A-band and I-band.

In Young's experiment, the pinholes are illuminated, by a monochromatic light of wavelength 5200 overset (@)(A) . A screen is placed at 1 m from the slit. If the pinholes are 1.3 mm apart, find i)fringe width ii) the distance between the seventh bright band on one side and sixth dark band on the other side of the central bright band.

In a biprism experiment the distance between the slit and the eyepiece is 100 cm. When a convex lens is introduced between the biprism and the eyepiece, images of the slit obtained in the two positions of the lens are 2 xx 10^-3 m and 4.5 xx 10^-3m apart.If the wavelength of light used is 6000 overset (@)(A) , find the distance between the fourth bright band on one side and fourth dark band on the other side of central bright band.
