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 9

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 50° to the normal. What is the angle between the incident ray and the reflected ray?

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

A ray of light strikes a mirror at an angle of 45° to the normal. What is the angle between the incident ray and the reflected ray?

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

A student shines a light ray at a mirror and measures the angle of incidence as 25°. What should the angle of reflection be according to the laws of reflection?

Describe the difference between regular and diffuse reflection.

Describe what happens to the direction of a light ray when it strikes a smooth, plane mirror at an angle.

Describe what is meant by the term 'normal' in the context 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.

Explain why the laws of reflection are important in designing periscopes.

Explain why you cannot see your reflection clearly in a rough wall.

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

If the angle between the mirror and the incident ray is 20°, what is the angle of incidence?

If the angle of incidence is 0°, what will be the direction of the reflected ray?

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

State the first law of reflection.

State the second law of reflection.

What is the angle between the incident ray and the reflected ray if the angle of incidence is 40°?

Which law of reflection explains why the image in a mirror appears upright?
