Total internal reflection can take place only if (a) light goes from optically rarer medium (smaller refractive index) to optically denser medium

(a) √3/√2 is the correct option

Answer: Regular reflection  Diffused reflection 1 When all the parallel rays reflected from a plane surface are parallel, the reflection is known as regular reflection When all the parallel rays reflected from a plane surface...

A medium in which light travels comparatively faster than the other medium is called an optically rarer medium.

A medium in which light travels comparatively slower than the other medium is called an optically denser medium.

The refractive index of alcohol is more than water, therefore, alcohol is optically denser medium.

(d) : According to Brewster's law of polarization, n = taniP where ip is angle of incidence Therefore, ip = tan–1(n).

(b) According to Snell’s Law,  sin i/ sin r =μ 2/μ 1 = where r = 90º for particular incidence angle called critical angle. When the incidence angle is equal to or greater than...

(c) For total internal reflection light ray must travel from optically denser to an optically rarer medium.

No; when light travels from a rarer to denser medium, its frequency remains unchanged. According to quantities theory, the energy of a light beam depends on frequency and not on...

(a) Total internal reflection is an optical phenomenon that happens when a ray of light strikes a medium boundary at an angle larger than a particular critical angle with respect...
