Define reflection and refraction of light.

Mention any three differences between reflection and refraction of light.

If a ray of light in a denser medium strikes a rarer medium at an angle of incidence i , the angle of reflection and refraction are respectively r and r', if the reflected and refracted rays are at right angles to each other, the critical angle for the given pair of media is

What is lateral refraction of light ?

Explain the refraction of plane wavefront of light through a prism.

Describe an activity to show refraction of light through a prism. Draw relevant figure, marking angle of incidence, refraction emergence, and deviation.
