Is there an angle of incidence between \(0^{\circ}\) and \(90^{\circ}\) such that all of the light will be reflected?

A. Yes, at an angle greater than \(50^{\circ}\)

B. Yes, at an angle less than \(50^{\circ}\)

C. No Are concerned with the situation sketched in Figure Q18.17, in which a beam of light in the air encounters a transparent block with index of refraction \(n=1.53\). Some of the light is reflected and some is refracted.
