MCQs-PYQs-12th-jee

Monochromatic light is incident on a glass prism of angle A. If the refractive index of the material of the prism is μ, a ray incident at an angle θ, on the face AB would get transmitted through the face AC of the prism provided

MCQs-PYQs-12th-jee

A triangular prism of glass is shown in the figure. A ray incident normally to one face is totally reflected. If θ=45, the refractive index of glass is :

MCQs-PYQs-12th-jee

In an experiment for determination of refractive index of glass of a prism by i – δ plot, it was found that a ray incident it an angle 35° suffers a deviation of 40° and that it emerges at an angle 79°. In that case, which of the following is closest to the maximum possible value of the refractive index?

MCQs-PYQs-12th-jee

Diameter of a plano-convex lens is 6 cm and thickness at the centre is 3 mm. If the speed of light in the material of the lens is 2 x10^8 m/s the focal length of the lens is

MCQs-PYQs-12th-jee

A thin convex lens made from crown glass (mu = 3/2) has focal length f. When it is measured in two different liquids having refractive indices 4/3 and 5/3 it has the focal length f1 and f2 respectively. The correct relation between the focal length is

MCQs-PYQs-12th-jee

A thin glass (refractive index 1.5) lens has optical power of -5D in air. It’s optical power in a liquid medium with refractive index 1.6 will be

MCQs-PYQs-12th-jee

The image of an object, formed by a plano-convex lens at a distance of 8 m behind the lens, is real and is one-third the size of the object. The wavelength of light inside the lens is 2/3 times the wavelength in free space. The radius of the curved surface of the lens is

MCQs-PYQs-12th-jee

A rectangular glass slab ABCD of refractive index n1 is immersed in water of refractive index n2 (n1 > n2 ). A ray of light is incident at surface AB of the slab as shown in Fig. What is maximum value of angle of incidence on AB such that the ray emerges out only from the surface CD?

MCQs-PYQs-12th-jee

A point source S is placed at the bottom of a transparent block of height 10 mm and refractive index 2.72. It is immersed in a lower refractive index liquid as shown in the figure. It is found that the light emerging from the block to the liquid forms a circular bright spot of diameter 11.54 mm on the top of the block. The refractive index of the liquid is

MCQs-PYQs-12th-jee

A fish looking up through the water sees the outside world contained in a circular horizon. If the refractive index of water is 4/3 and the fish is 12 cm below the surface, the radius of this circle in cm is
