REFRACTION OF LIGHT IS DEFINED AS THE BENDING LIGHT.WHEN LIGHT PASSES

FROM ONE MEDIUM INTO ANOTHER,IT CHANGES DIRECTION.SO,WHY DOES LIGHT BEND?
LIGHT TRAVELS WITH DIFFERENT SPEEDS IN DIFFERENT MEDIUMS.ITS SPEED IS 300000KM/S IN AIR,225000KM/S IN WATER AND 200000 IN GLASS. THEREFORE,WHEN IT PASSES FROM AIR INTO WATER IT SLOWS DOWN.

$Laws of Refraction: •The incident light,the reflected light and the normal$

Laws of Refraction:
•The incident light,the reflected light and the normal are

all in the same plane.
•Light passing from an optically less dense medium into a denser medium bends towards the normal.
•Light passing from an optically denser medium into a less dense medium bends away from the normal.
-The angle of incidence is the angle between incident Ray and the normal.The angle of refraction is the angle between refracted Ray and the normal.

BUT REMEMBER THAT:
IF A LIGHT RAY IS EXACTLY PERPENDICULAR TO THE

SURFACE IT DOES NOT BEND.

Misconceptions caused by the refraction of light??

Misconceptions about light include the nature of light, the speed at which light travels, the behavior of light, image formation, and color. In keeping with our focus on the albedo effect, we focus on the reflection and absorption of light as well as the light from the sun.
