rarer medium to denser medium.
B) Light ray makes an angle of zero degree with the normal while tra
denser medium to rarer medium.
C) Light ray makes a small angle with the normal while traveling fra
rarer to denser medium.

Answer 2

Answer:

Lights makes an angle of 0 degree with the normal while travelling from rear to denser medium will not change its direction because normally when light moves from rear to denser medium it bends toward the normal but here the angle of light with the normal is 0 degree so there is no chance to bend the light towards the normal so A is the correct answer
