For constructive interference to take place between two monochromatic light waves of wavelength lambda , the path difference should be

Two small angled transparent prisms (each or refracting angle A = 1^(@)) are so placed that their bases coincide, so that common base is BC. This device is called Fresnel's biprism and is used to obtain coherent sources of a point source S illuminated by monochromatic light of wavelength 6000 Å placed at a distance a = 20 cm. Calculate the separation between coherent sources. If a screen is placed at a distance b = 80 cm. from the device, what ist the finge which of fringes obtained (Refractive index of material of each prism = 1.5.)

Consider the situation shown in figure. The two slite S_1 and S_2 placed symmetrically around the centre line are illuminated by a monochromatic light of wavelength lambda. The separation between the slits is d. The light transmitted by the slits falls on a screen M_1 placed at a distance D from the slits. The slit S_3 is at the centre line and the slit S_4 is at a distance y form S_3 . Another screen M_2 is placed at a further distance D away from M_1 . Find the ration of the maximum to minimum intensity observed on M_2 if y is equal to (dltltD) .

Consider the situation shown in figure. The two slits S_1 and S_2 placed symmetrically around the central line are illuminated by a monochromatic light of wavelength lamda . The separation between the slits is d. The light transmitted by the slits falls on a screen Sigma_1 placed at a distance D from the slits. The slit S_3 is at the placed central line and the slit S_4 , is at a distance z from S_3 . Another screen Sigma_2 is placed a further distance D away from 1,1.
