Write equation of refractive index of from refraction through prism.

What is the unit of refractive index?

A glass prism of angle A = 60^(@) gives minimum angle of deviation theta ~~ 30^(@) with the maximum error of 1^(@) when a beam of parallel light passed through the prism during an experiment. Find the permissible error in the measurement of refractive index mu of the material of the prism.

Write Snell.s law for refraction

The angle of incidence for a ray of light at a refracting surface of a prism is 45^@ . The angle of prism is 60^@ . If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are

When a ray of light enters into the medium of refractive index of mu , angle of refraction is half of angle of incidence so angle of incidence = ......

In an experiment for determination of refractive index of glass of a prism by i-delta , plot it was found thata ray incident at angle 35^circ , suffers a deviation of 40^circ and that it emerges at angle 79^circ . In that case which of the following is closest to the maximum possible value of the refractive index?

Obtain the relation between incidence angle, emergence angle, prism angle and deviation angle for refraction through prism

A convex lens is immersed in a liquid, whose refractive index is equal to the refractive index of the material of the lens. Then its focal length will

The relative refractive index of water with respect to air is Then relative refractive index of air with respect to water is

A horizontal ray is incident on a right-angled prism with prism angle of 4o. If the refractive index of material of the prism is 1.5, angle of emergence is .......... . Use the given figure.
