MCQs-PYQs-12th-jee

For a normal eye, the cornea of eye provides a converging power of 40 D and the least converging power of the eye lens behind the cornea is 20 D. Using the information, the distance between the retina and the cornea eye lens can be estimated to be

MCQs-PYQs-12th-jee

The refractive index of the material of a prism is √2 and the angle of the prism is 30°. One of the two refracting surfaces of the prism is made a mirror inwards, by silver coating. A beam of monochromatic light entering the prism from the other face will retrace its path (after reflection from the silvered surface) if its angle of incidence on the prism is.

MCQs-PYQs-12th-jee

A thin prism having refracting angle 10º is made of glass of refractive index 1.42. This prism is combined with another thin prism of glass of refractive index 1.7. This combination produces dispersion without deviation. The refracting angle of second prism should be

MCQs-PYQs-12th-jee

A thin prism of angle 15° made of glass of refractive index μ₁ = 1.5 is combined with another prism of glass of refractive index µ₂ = 1.75. The combination of the prisms produces dispersion without deviation. The angle of the second prism should be

MCQs-PYQs-12th-jee

The refracting angle of a prism ‘A’, and refractive index of the material of the prism is cot(A/2). The angle of minimum deviation I

MCQs-PYQs-12th-jee

For a prism of refractive index 1.732, the angle of minimum deviation is equal to the angle of the prism. The angle of the prism is

MCQs-PYQs-12th-jee

Angle of a prism is 30° and its refractive index is √2 and one of the surfaces is silvered. At what angle of incidence, a ray should be incident on one surface so that after reflection from the silvered surface, it retraces its path

MCQs-PYQs-12th-jee

A ray of light is incident at an angle of incidence i, on one face of a prism of angle A (assumed to be small) and emerges normally from the opposite face. If the refractive index of the prism is n the angle of incidence i, is nearly equal to

MCQs-PYQs-12th-jee

For the angle of minimum deviation of a prism to be equal to its refracting angle, the prism must be made of a material whose refractive index

MCQs-PYQs-12th-jee

The angle of incidence for a ray of light at a refracting surface of a prism is 45°. The angle of prism is 60°. If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively,are
