A biprism is placed 5 cm from a slit illuminated by sodium light (5890 A). The fringe width
obtained on the screen is 0.9424mm. The screen is at a distance of 75 cm from the biprism.
Find the distance between the two coherent sources (Ans: 0.5 cm)
A convex lens is placed between the Fresnel's biprism and the screen. At oune of its position
he distance of separation between the images of the coherent sources is 0.6 mm whereas at
inother position, the distance of separation is 0.27 mm. What is the distance between the two
oherent sources? (Ans: 4.025 X 10 m. Pg 140. S.Chand)
