The angle between incident ray and reflected ray or refracted ray is called _____

A ray incident at a point at an angle of incidence of 60^(@) enters a glass sphere with refractive index sqrt(3) and it is reflected and refracted at the farther surface of the sphere. The angle between the reflected and refracted rays at this surface is:

The angle of incidence on the surface of a diamond of refractive index 2.4, if the angle between the reflected and refracted rays is 90° is

Unpolarized light is incident on a plane glass surface. What should be the angle of incidence so that the reflected and refracted rays are perpendicular to eachother ?

A ray of light is incident on a glass plate of refractive index 1.5. The angle between the reflected and refracted rays is 90^(@) . What is the ratio of wavelenth of reflected to refracted rays?
