Reflection of Light
Physics ⇒ Light and Optics
Reflection of Light 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 Reflection of Light.
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 periscope uses two plane mirrors. What is the angle between the mirrors in a typical periscope?
A ray of light is incident at 30° 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 45°. What is the angle between the incident ray and the reflected ray?
A ray of light strikes a mirror at an angle of 60° to the normal. What is the angle between the incident ray and the mirror surface?
A ray of light strikes a plane mirror at an angle of 20° with the mirror surface. What is the angle of reflection?
A student shines a torch at a mirror and measures the angle of incidence as 25°. What should be the angle of reflection?
Define the term 'normal' in the context of reflection of light.
Describe what happens to the direction of light when it reflects off a smooth surface.
Describe what happens to the image of an object as it moves closer to a plane mirror.
Explain the difference between regular and diffuse reflection.
Explain why the image in a plane mirror appears to be behind the mirror.
Explain why you cannot see your reflection clearly in a piece of paper.
If a person moves 1 m closer to a plane mirror, by how much does the distance between the person and their image decrease?
If a person stands 2 m in front of a plane mirror, what is the distance between the person and their image?
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?
What is meant by lateral inversion?
What is the angle of reflection if a ray of light strikes a mirror at 0° to the normal?
