Question

Answer 1

Answer #1

n1 n2 1 Apply Snell's law of reflection

$n_{1}sin i=n_{2}sinr$

i and r are the angle of incidence and angle of reflection from the normal

The ray is moving away from the normal. i.e.

angle r > angle i

Therefore n2 is rarer medium with respect to n1.

n1>n2

Hence the given statement that n1<n2 is False.
