A ray light fall on a plane surface at an angle of incidence `9^@` and reflection occurs. Calculate the angle of reflection in degree.

Reflection occurs, when the light

A ball of mass 50 g moving at a speed of 2.0 m/s strikes a plane surface at an angle of incidence 45^0 . The ball is reflected by the plane at equal angle of reflection with the same speed. Calculate a. the magnitude of the change in momentum of the ball b. the change in the magnitude of the momentum of the wall.

If a ray of light is falling on a plane mirror at an angle of 50^@ is formed , what will be the angle of reflection?

Each photon has a linear momentum h/lamda where h is the Planck's constant and lamda is the wavelength lamda is incident on a plane mirror at an angle of incidence theta . Calculate the change in the linear momentum of a photon as the beam is reflected by the mirror.

Light rays travel from vacuum into glass whose refractive index is 1.5 If the angle of incidence is 30^(@) calculate the angle of refraction inside the glass.

What is angle of deviation due to reflection?
