Top Questions on Ray optics and optical instruments
- Two equilateral-triangular prisms \(P_1 \)and \(P_2\) are kept with their sides parallel to each other, in vacuum, as shown in the figure. A light ray enters prism \(P_1\) at an angle of incidence 𝜃 such that the outgoing ray undergoes minimum deviation in prism \(P_2\). If the respective refractive indices of \(P_1\) and\( P_2\) are \(√ 3 /2\) and \(√3\), then \(\theta = sin{−1}[\sqrt \frac{ 3}{ 2} sin ( \frac{\pi}{B} )],\) where the value of \(\beta\) is ______.

Concepts Used:
Prism
A homogeneous solid transparent and refracting medium bounded by 2 plane surfaces inclined at an angle called prism. The prism has two triangular faces that are parallel to each other and 3 rectangular surfaces. They are made from glass or other transparent material cut with accurate angles. Out of three, two rectangular faces are polished and are called refracting surfaces. The angle between these two rectangular faces is known as the refractive angle of the prism.
Depending on the application, prisms are made in different shapes. Triangle is the traditional shape of the prism. The triangular prism, when passed through the prism, separates the white light into constituent colors.
Five types of Prism are:
- Dispersive Prism
- Reflective Prism
- Polarizing Prism
- Beam-Splitting Prism
- Deflecting Prism
