Question

when light travels from an optically denser medium to a rarer medium, a. It bends away from the normal b. It bends towards the normal. c.it is undeviated
d. It is laterally displaced.​

Answer 1

Answer:

b.It bends away from the normal

Explanation:

Tjhis happens due to the change of speeds when light travels from one medium to another.

Answer 2

Answer:As the light goes from an optically denser to an optically rarer medium, it bends away from the normal. Hence, the angle of refraction is greater than the angle of incidence. For optically denser medium, the refractive index n1​ is greater than that of the rarer medium n2​.

When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left. This behavior follows from Snell's Law. As you saw before, the larger angle must be in the medium having the lower index of refraction.
