A ray of light passing from glass to water is incident on the glass-water interface at 65^{\circ}. If the critical angle for the pair of media is 63^{\circ}.

Correct Answer is : The ray will be totally internally reflected back into glass with a deviation of 50∘

The ray will emerge into water with a deviation of 2^{\circ} from the normal

The ray will be refracted into water with a deviation of 2^{\circ}

The ray will be totally internally reflected back into glass with a deviation of 50^{\circ}

The ray will be totally internally reflected back into glass with a deviation of 2^{\circ}
