A beam of light is converging towards a point. A plane parallel plate of glass of thickness t, refractive index `mu` is introduced in the path of the beam. The convergent point is shifted by (assume near normal incidence) :

A beam of light is converging towards a point I on a screen. A plane glass plate whose thickness in the direction of the beam =t , refractive index =mu , is introduced in the path of the beam. The convergence point is shifted by A. t(1-1/(mu)) away B. t(1+1/(mu)) away C. t(1-1/(mu)) nearer D. t(1+1/(mu)) nearer

When a transparent parallel plate of uniform thickness t and refractive index mu is interposed normally in the path of a beam of light, the optical path is

A double slit experiment is performed with light of wavelength 500nm . A thin film of thickness 2mum and refractive index 1.5 is introduced in the path of the upper beam. The location of the central maximum will

In a Young.s double slit experiment, the fringes are displaced by a distance x when a glass plate of refractive index 1.5 is introduced in the path of one of the beams. When this plate is replaced by another plate of same thickness, the shift of fringes is (3"/"2)x . The refractive index of second plate is

A beam of light is incident at the polarizing angle of 35^(@) on a certain glass plate. The refractive index of the glass plate is:

A beam of light converges at a point P. Draw ray diagram to show where the beam will converge if (i) a convex lens and (ii) a concave lens is kept in the path of the beam?

A ray of light is incident on a parallel slab of thickness t and refractive index n. If the angle of incidence theta is small, than the lateral displacement in the incident and emergent ray will be

Light travels through a glass plate of thickness t and refractive index mu. If c is the speed of light in vacuum, the time taken by light to travel this thickness of glass is

Figure given below shows a beam of light converging at point P. When a concave lens of focal length 16cm is introduced in the path of the beam at a place O shown by dotted line such that OP becomes the axis of the lens, the beam converges at a distance x from the lens. The value x will be equal to

Young's double-slit experiment is conducted in water (mu_(1)) as shown in figure and a glass plate of thickness t and refractive index mu_(2) is placed in the path of S_(2) . Find the magnitude of the optical path difference at 'O'.
