Explain refraction. Draw a diagram and explain incident ray, refracted ray, angle of incidence, and angle of refraction.

Draw diagrams to show the refraction of light from (i) air to glass, and (ii) glass to air. In each diagram, label the incident ray, refracted ray, the angle of incidence (i) and the angle of refraction (r).

Draw a diagram to show the reflection of a ray of light by a plane mirror. In the diagram, label the incident ray, the reflected ray, the normal, the angle of incidence and the angle of reflection.

Draw a diagram to show refraction through a glass slab and label the following: (a) incident ray (b) refracted ray (c) emergent ray (d) angle of incidence (e) angle of refraction at the first boundary of two mediums (f) angle of emergence and (g) lateral displacement

The angle between the incident ray and the refracted ray of a prism is called angle of deviation.

The diagram alongside shows the refraction of a ray of light from air to a liquid. (a) Write the values of (i) angle of incidence, and (ii) angle of refraction. (b) Use snell's law to find the refractive index of liquid with respect to air.

A plane wavefront propagating from a rarer into a denser medium is incident at an angle of incidence i on a refracting surface. Draw a diagram showing incident wavefront and refracted wavefront . Hence verify Snell's laws of refraction.

A ray of light is incident on the surface of a glass plate of refractive index sqrt(3) at the polarising angle . The angle of incidence and angle of refraction of the ray is

Define the following with reference to refraction of light. (a) incident ray, (b) refracted ray ( c ) normal, (d) emergent ray, ( e ) angle of incidence, (br> (f) angle of refraction.

A ray of light passes from vaccum into a medium of refractive index n. If the angle of incidence is twice the angle of refraction, then the angle of incidence is

The incident ray, the _______ ray and the normal lie in the same plane during refraction.
