In case of refraction of light for normal incidence, there is no deviation because

Assertion: Ray of light passing through optical centre of a lens goes undeviated. Reason: Ray falls normal at optical centre and in normal incidence, there is no deviation of light.

Assertion: Ray of light passing through optical centre of a lens goes undeviated. Reason: Ray falls normal at optical centre and in normal incidence, there is no deviation of light.

Light rays from a source are incident on a glass prism of index of refraction mu and angle of prism alpha At near normal incidence, the angle of deviation of the emerging rays is

Assertion : Any ray of light suffers a deviation of (180^@-2i) after one reflection. Reason : For normal incidence of light deviation is zero.

Assertion : Any ray of light suffers a deviation of (180^@-2i) after one reflection. Reason : For normal incidence of light deviation is zero.

In case of refraction, angle of deviation becomes minimum when the angle of incidence becomes

What is the angle of deviation due to refraction of a ray of light incident perpendicularly on a refraction surface?

Light incident on an equilateral prism of refractive inden sqrt2 suffers minimum angle of deviation. The angle of incidence and minimum angle of deviation are (in degree)

The refractive index of a medium with respect to air is sqrt2 . If the angle of incidence of a ray of light in air is 45^@ determine the angle of deviation for that ray in case of refraction.
