Question

In the following figure, mark the correct light as it travels through different mediums.

Answer 1

As shown in figure the light travels from glass (denser medium) to air (rarer medium).

So, when light travel from denser medium to rarer medium then it will bend away from normal

means, $\angle i<\angle r\frac{1}{\mu }=\frac{sini}{sinr}$

$i=$ angle of incidence in glass

$r=$ angle of refraction in air

Thus from the given figure the refracted ray is A.
