The critical angle for a beam of light passing from water into air is 48.7°. This means that all light rays with an angle of incidence in the water that is greater than 48.7° will be: A. totally reflected at an angle equal to the incident angle B. totally reflected at an angle smaller than the incident angle C. totally absorbed by the water. D. totally transmitted through the interface. E. partially reflected and partially transmitted.

A ray of light travelling in glass having refractive index ${ }_{a} \mu_{\mathrm{g}}=3 / 2$, is incident at a critical angle $\mathrm{C}$ on the glass-air interface. If a thin layer of water is poured on glass air interface, then what will be the angle of emergence of this ray in air when it emerges from water-air interface? (a) $180^{\circ}$ (b) $0^{\circ}$ (c) $90^{\circ}$ (d) $45^{\circ}$

Light in water is incident on the water-air interface (nwater = 1.33; nair = 1). Which of the below statements is incorrect? Select one: Any incident angle bigger than the critical angle (θc) will produce a total internal reflection. Any incident angle smaller than the critical angle (θc) will produce a total internal reflection. The critical angle (θc) is the incident angle corresponding to an angle of refraction of 90°.

00:01 So when we have a theta -critical, that's the angle at which refraction can still occur.

00:08 So if we have an angle of incidence from one medium to another, that's greater than our critical angle, all light undergoes total internal reflection.

00:17 That means all of the light is going to be totally reflected if our incident angle is greater than the theta -critical...
