View Solution. Q 4. Answer the following questions: (a) What is total internal reflection? (b) State two conditions necessary for the total internal reflection to occur. (c) Draw diagrams to illustrate the total internal reflection. View Solution. Q 5.
For total internal reflection to take place (i) light must travel from a denser medium to a rarer medium and (ii) the angle of incidence inside the denser medium must be greater than the critical angle. i.e., ∠i>∠c. Was this answer helpful?
A ray of light travelling in air strikes the glass surface at an angle of incidence 60∘. Find the angle of refraction in glass if refractive index of glass is 3 2? (given sin60∘ = √3 2 and sin35∘ = 1 √3) View Solution.
Kelper used total internal reflection in a glass block to deflect a beam of light as shown in the figure. For an angle of the incidence i at the top surface, the minimum refractive index (n) needed for total internal reflection at the vertical surface is (the surrounding medium is air for which n = 1)

Consider the set up shown in the figure, which uses a right-angled prism to transmit a horizontal incident ray. This device is known as anamorphic de-magnifier. During its passage through the prism, the ray experience total internal reflection $$(TIR)$$ twice and then exits as shown in the figure.

Solution. Verified by Toppr. When a light travelling in a denser medium, is incident at the surface of a rarer medium such that the angle of incidence is greater than the critical angle for the pair of medium, the ray is totally reflected back into the denser medium. This phenomenon is called the total internal reflection.
