List of top Physics Questions on Refraction of Light asked in MHT CET

A glass cube of length 21 cm has a small air bubble trapped inside. When viewed normally from one face, the bubble appears to be at 12 cm. When viewed normally from the opposite face, its apparent distance is 6 cm. The refractive index of glass and the actual distance of the air bubble from the first surface respectively are \dots
Note: Based on standard physical constraints, there is a known typographical error in the standard transcript of this exam question. To yield $\mu \approx 1.5$ (glass), the apparent depth from the first face was intended to be 8 cm, not 12 cm. We will demonstrate the solution finding the closest logical answer based on standard glass refraction values.

A monochromatic ray of light is incident normally on a thin prism of refracting angle A. The ray is deviated through an angle $(1.15)^\circ$ in passing through the prism. The ray reflected internally from the second face emerges from the first face making an angle of $(6.3)^\circ$ with the incident ray. The refractive index of the prism is ______.

Refractive index of a glass convex lens is 1.5. The radius of curvature of each of the two surfaces of the lens is 40 cm. The ratio of the power of the lens when immersed in a liquid of refractive index 1.25 to that when placed in air is

A ray of light travels from air to water to glass and again from glass to air. Refractive index of water w.r.t. air is 'X', glass w.r.t. water is 'Y' and air w.r.t. glass is 'Z'. Which one of the following is correct?

A plano-convex lens of refractive index $\mu_1$ fits exactly into a plano-concave lens of refractive index $\mu_2$. Their plane surfaces are parallel to each other. 'R' is the radius of curvature of the curved surface of the lenses. The focal length of the combination is

A glass slab has refractive index $\mu$ with respect to air and the critical angle for a ray of light in going from glass to air is $\theta$. If a ray of light is incident from air on the glass with angle of incidence $\theta$, then the corresponding angle of refraction is
