Question

.Assertion(A): In case of rainbow, light at the inner surface of the water drop
get internally reflected.
Reason (R): The angle between the refracted ray and normal to the drop
surface is greater than the critical angle. who will tell first will be brainliest

Answer 1

Answer:

HEY MATE YOUR ANSWER IS

Explanation:

BOTH THE ASSERTION AND REASON IS TRUE

Answer 2

The correct answer is (a) Both A and R are correct and A is the correct explanation of R

• When a ray of white light is incident on a drop of water, it suffered refraction at the outer surface of the water drop. At the inner surface of the water drop, it undergoes total internal reflection.
• The light is split into seven colours inside the drop and a rainbow is formed.
• The reason that the white light is split is because of total internal reflection. Total internal reflection occurs because the angle between the refracted ray and the normal to the drop is greater than the critical angle.
• And as we know, if the incidence angle is greater than the critical angle, the total internal reflection will take place.
• Thus, the reason statement explains the assertion statement.
