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 11
A periscope uses two plane mirrors placed parallel to each other. If the angle of incidence on the first mirror is 45°, what is the angle of reflection from the second mirror?
A person moves 1 m closer to a plane mirror. By how much does the distance between the person and their image decrease?
A person stands 2 m in front of a plane mirror. What is the distance between the person and their image?
A ray of light is incident at 30° to the normal on a plane mirror. What is the angle between the incident and reflected rays?
A ray of light is incident on a plane mirror at an angle of 45° to the surface. What is the angle of incidence?
A ray of light strikes a plane mirror at an angle of 35° to the normal. What is the angle between the incident ray and the reflected ray?
Describe the orientation of the image formed by a plane mirror with respect to the object.
Describe what happens to the direction of a light ray when it strikes a rough surface.
Explain the difference between regular and diffuse reflection.
Explain why the image in a plane mirror appears to be laterally inverted.
Explain why you cannot see your reflection clearly in a piece of paper.
If a plane mirror is rotated by 10°, by how many degrees does the reflected ray rotate?
If a ray of light is incident on a plane mirror at an angle of 20° to the normal, what is the angle of reflection?
If the angle between the incident ray and the mirror is 60°, what is the angle of reflection?
If the angle of incidence is 0°, what will be the angle of reflection?
State the law of reflection of light.
