Question

A ray of light incident at an angle θ on a refracting face of a prism
emerges from the other face normally. If the angle of the prism is 5°
and the prism is made of a material of refractive index 1.5, the angle
of incidence is

Answer 1

Explanation:

Hydrogen is the chemical element with the symbol H and atomic number 1. With a standard atomic weight of 1.008, hydrogen is the lightest element in the periodic table. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all baryonic mass.

Answer 2

Explanation:

Again, by Snell's law, we have that the ratio of sine of angle of incidence and the angle of refraction is always a constant and it is the basic property of that medium. It is called the refractive index of that medium. Hence, the angle of incidence on the face of the prism is 7.5∘ .
