What is partial reflection?

A beam of light is partially reflected and partially refracted from a surface. The angle between reflected and refracted light ray is 90^(@) . If the angle of refraction is 30^(@) , the angle of incidence is

What is total internal reflection?

Questions based on diagram : Draw a figure describing the following : The reflecting surfaces of two mirrors make an angle of 90⁰ with each other . If a ray incident of one mirror has an angle of incidence of 30⁰ , draw the ray reflected from the second mirror . what will be its angle of reflection ?
