Question

A ray of light goes from water into air. Will it bend towards the normal or away from the normal?

Answer 1

Light ray will bend away from normal.

Explanation:

when the light ray goes from water to air it will bends away from normal because the the refractive index of water (1.34) is greater than refractive index of air (1.003). in this case incidence angle of ray is less than the refractive angle of ray and the ray has greater velocity in rare medium than denser medium so the light ray travels from denser to rare medium it will bend towards the the imaginary line between two different media or you can say that it bends away from the normal.  

Answer 2

Ray bends away from Normal

Explanation:

• When a ray of light travels from a denser medium (water) to a rarer medium (air), it bends away from the normal.

• Therefore, the ray of light will bend away from the normal in the given case.
