Find the deviation produced by reflection at a plane mirror when the angle between the incident and reflected' rays is 80?

What is incident ray and reflected ray?

Shape of reflection create on plane mirror____

A ray of light travelling through a denser medium is incident at an angle I in a rarer medium. If the angle between the reflected ray and refracted ray is 90^(@) , show that the critical angle of the two media, theta_(c) = sin^(-1) (tan i)

A ray of light is reflected by a plane mirror. hatepsilon_(0), hate and hatn be the unit vectors along the incident ray, reflected ray and the normal to the reflecting surface respectively. Which of the following gives an expression for hate ?

A ray of light is incident on a glass sphere and it makes an angle alpha with the normal, and then it is refracted at an angle beta . Calculate the angle of deviation between the incident and emergent ray.

An unpolarised light is incident at angle of polarisation on a reflector. Determine the angle between the reflected and the transmitted rays.

(i) State Brewster's law. (ii) An unpolarised light is incident at angle of polarisation on a reflector. Determine the angle between the reflected and the transmitted rays.

A ray of light enters a rectangular glass block and is incident on the lower face of the block. Angle of incidence is 30^(@) . Part of the ray is reflected inside it and the rest emerges out of the block. Refractive index of glass is 1.5. What is the angle between the emergent ray and the reflected ray? [sin 48^(@) = 0.75]

The angle between the normal and incident ray is known as ______.
