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 12
A light ray strikes a plane mirror at an angle of 20° with the normal. What is the angle between the incident and reflected rays?
A periscope uses two plane mirrors placed at 45° angles. Explain how the law of reflection allows the periscope to work.
A person moves 1 m closer to a plane mirror. By how much does the distance between the person and his image decrease?
A person stands 2 m in front of a plane mirror. What is the distance between the person and his image?
A ray of light is incident at 45° 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 60° to the mirror surface. What is the angle of incidence?
A ray of light strikes a plane mirror at an angle of 35° with the normal. What is the angle between the incident and reflected rays?
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 rough surface.
Explain the difference between regular and diffuse reflection.
Explain why a mirror needs to have a smooth surface to form a clear image.
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 much does the reflected ray rotate?
If the angle between the incident ray and the mirror surface is 40°, what is the angle of reflection?
If the angle of incidence is 25°, what is the angle of reflection?
State the law of reflection of light.
