(a) Explanation Given info: The angle of incidence is 45 ° . Explanation: The formula to calculate the Snell’s law is, n 1 sin θ i = n 2 sin θ r Here, n 1 is the refractive index of air. n 2 is the refractive index of sphere. θ i is the angle of incidence. θ r is the angle of refraction. Rearrange the above formula for n 2 . n 1 sin θ 1 = n 2 sin θ 2 n 2 = n 1 sin θ 1 sin θ 2 From the above figure, the angle of refraction is half of the angle of incidence (b) To determine whether the index of refraction is finite that will make the three beams come to a focus at the centre of sphere or not.

Refraction of Light

Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.

Angle of Refraction

Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic…

A drop of water (n=1.33) in the shape of a hemisphere with radius 3.0 mm sits on smooth horizontal surface of a sapphire (n=1.77). A thin laser beam enters the droplet from air and reaches the water-sapphire boundary at the exact center of their circle of contact. At that point, laser beam is completely reflected off the surface of the sapphire. a. What is the maximum height above the sapphire that the laser beam could enter the droplet to be internally reflected at the center of the droplet as described above? b. What is the angle of incidence as the beam enters the droplet?
