Question:
Express refractive index of Medium 2 with respect to Medium 1 in terms of speed of light in two media.
Express refractive index of Medium 2 with respect to Medium 1 in terms of speed of light in two media.
Show Hint
The refractive index of a medium is the ratio of the speed of light in vacuum to the speed of light in that medium. The bending of light depends on the relative speed in different media.

Solution and Explanation
The refractive index of Medium 2 with respect to Medium 1 is given by the formula: \[ n_{2/1} = \frac{c_1}{c_2} \] Where:
- \( c_1 \) is the speed of light in Medium 1,
- \( c_2 \) is the speed of light in Medium 2.

- A rectangular glass slab ABCD (refractive index 1.5) is surrounded by a transparent liquid (refractive index 1.25) as shown in the figure. A ray of light is incident on face AB at an angle \(i\) such that it is refracted out grazing the face AD. Find the value of angle \(i\).
- An air bubble is trapped at point P (CP = 1.75 cm) in a spherical glass ball (n = 1.5) of radius 7 cm as shown in the figure. Find the nature and position of the image when viewed from side B. Show the image formation by drawing a ray diagram.
Give reasons:
(i) The sky appears dark to passengers flying at very high altitudes.
At very high altitudes, passengers are above the atmosphere where there is less scattering of sunlight. As a result, they do not see the scattered blue light and the sky appears dark, similar to the condition experienced by astronauts in space.
(ii) 'Danger' signal lights are red in color.- CBSE Class X - 2025
