• 15 degree

• 30degree

• 46 degrees

If a ray of light strikes a mirror at a 45° angle what will be the angle of reflection

• 0°

• 90°

• 45°

Which of the following surface will follow the law of reflection

The angle of incidence and angle of reflection are measured with respect to

• The surface

• The normal line

• The reflected ray

In law of reflection the incidence ray the reflected ray and normal all lie in the

same
