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 10
A light ray strikes a mirror at an angle of 25° to the normal. What is the total angle between the incident and reflected rays?
A ray of light is incident at 40° to the normal. If the mirror is rotated by 10° while keeping the incident ray fixed, by how much does the reflected ray rotate?
A ray of light is incident on a mirror at 60° to the surface. What is the angle of incidence?
A ray of light is incident on a plane mirror at 15° to the normal. What is the angle between the incident ray and the mirror surface?
A ray of light is incident on a plane mirror at 30° to the normal. If the mirror is rotated by 5° in the direction of the incident ray, what will be the new angle of reflection?
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 plane mirror at an angle of 35° to the normal. What is the angle of reflection?
A student shines a light ray at a mirror and measures the angle of incidence as 50°. What should the angle of reflection be according to the laws of reflection?
Describe the path of a light ray that strikes a plane mirror at an angle of 0° to the normal.
Describe what happens to the direction of a light ray when it strikes a mirror at an angle of 45° to the normal.
Describe what happens to the reflected ray if the angle of incidence is increased.
Explain the difference between regular and diffused reflection.
Explain why a rough surface does not produce a clear image even though it reflects light.
Explain why the laws of reflection are considered universal for all types of reflecting surfaces.
Explain why you can see your image in a still pond but not in a rough sea.
If a ray of light is incident at 20° to the normal, what is the angle between the incident and reflected rays?
If the angle of incidence is 0°, what will be the angle of reflection?
State the two laws of reflection.
