List of top Physics Questions on Total Internal Reflection asked in CUET (UG)

Arrange the following in the correct order as the angle of incidence in a denser medium is gradually increased. (A) The refracted ray bends away from the normal. (B) The refracted ray grazes along the surface of separation. (C) The light is totally reflected back into the denser medium. (D) The ray passes undeviated when incident normally. Choose the correct answer from the options given below:

Light is incident on an interface between water (refractive index \(=1.33\)) and glass (refractive index \(=1.5\)). For total internal reflection, light should be travelling from \[ (i_c \text{ is the critical angle}) \]

The critical angle of incidence \(i_c\) for a ray incident from a denser to rarer medium, is that angle for which

Which of the following statements are correct?
(A) Total internal reflection occurs when a ray of light travels from a rarer transparent medium to a denser medium.
(B) In total internal reflection, the incident ray of light remains in the same medium after reflection.
(C) In total internal reflection, the angle of incidence inside the denser transparent medium is equal to the angle of reflection in the same medium.
(D) In total internal reflection inside a denser medium there is no angle of refraction
Choose the correct answer from the options given below:

Light is traveling from one medium to another medium as given in the options. In which of the following options total internal reflection will be possible?
