Question

A ray of light traveling in air falls on the surface of
water. The angle of incidence is 60° with the
normal to the surface. The refractive index of
water = 3. Calculate the angle of refraction. ​

Answer 1

Answer:

We know that refractive index of air is 1

Here the incidence angle is i=53°

Using snell's law

n air sini=nglass sinr

sin53=1.6sinr

4/5=1.6sinr

r=30°

Answer 2

Explanation:

: Hunter-gatherers traveled from place to place in search of food. Once food resources at a place were exhausted, they needed to go to a new place. ... Some people travel because they enjoy travelling
