Correct option is B
The correct answer is
(b) Towards the normal.
· When light rays pass from a less dense medium (air) into a denser medium (glass), they slow down and bend
towards the normal. This is due to the change in speed as light enters a medium with a higher refractive index, which causes the light to change direction.
formation Booster:
·
Refraction: Refraction is the bending of light as it passes from one medium to another with a different density. The amount of bending depends on the refractive indices of the two media.
·
Normal: The normal is an imaginary line perpendicular to the surface at the point of incidence where the light ray enters the new medium.
·
Snell's Law: The relationship between the angle of incidence and the angle of refraction is given by Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant and equals the refractive index of the two media.
