Laws of Reflection

Physics ⇒ Light and Optics

Laws of Reflection starts at 7 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Laws of Reflection. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

See sample questions for grade 12

A light ray strikes a mirror at an angle of 25° to the normal. What is the angle between the incident ray and the mirror surface?

A light ray strikes a plane mirror at an angle of 15° to the normal. What is the angle between the incident ray and the mirror surface?

A ray of light is incident at 30° to the normal. What is the angle between the incident ray and the reflected ray?

A ray of light is incident at 45° to the normal on a plane mirror. What is the total angle between the incident and reflected rays?

A ray of light is incident on a plane mirror at an angle of 70° with the mirror surface. What is the angle of incidence?

A ray of light strikes a plane mirror at an angle of 60° with the mirror surface. What is the angle of reflection with respect to the normal?

Describe the difference between regular and diffuse reflection with respect to the laws of reflection.

Describe what happens to the direction of a light ray when it is incident perpendicular to a plane mirror.

Explain why a rough surface does not produce a clear image even though it obeys the laws of reflection.

Explain why the image formed by a plane mirror appears to be the same distance behind the mirror as the object is in front of it, using the laws of reflection.

Explain why the laws of reflection are valid for both regular and diffuse reflection.

If a ray of light is incident normally on a plane mirror, what is the angle of reflection?

If the angle between the incident ray and the reflected ray is 80°, what is the angle of incidence?

If the angle of incidence is 35°, what is the angle of reflection?

State the two laws of reflection.
