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
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.
State the law of reflection of light.
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?
Which of the following best describes the image formed by a plane mirror? (1) Diminished (2) Magnified (3) Same size as object (4) Variable size
Which of the following is an example of diffuse reflection? (1) Reflection from a calm lake (2) Reflection from a mirror (3) Reflection from a white wall (4) Reflection from a polished metal surface
Which of the following is NOT a characteristic of the image formed by a plane mirror? (1) Virtual (2) Laterally inverted (3) Same size as object (4) Real
Which of the following is NOT true about the image formed by a plane mirror? (1) It is virtual. (2) It is the same size as the object. (3) It is formed behind the mirror. (4) It can be captured on a screen.
Fill in the blank: The angle between the incident ray and the reflected ray is ______ times the angle of incidence.
Fill in the blank: The image formed by a plane mirror is ______ inverted.
Fill in the blank: The incident ray, the reflected ray, and the normal all lie in the same ______.
Fill in the blank: The normal is a line drawn ______ to the reflecting surface at the point of incidence.
True or False: The angle of incidence is always equal to the angle of reflection for a plane mirror.
True or False: The image formed by a plane mirror is always at the same distance behind the mirror as the object is in front of it.
True or False: The image formed by a plane mirror is always upright.
True or False: The laws of reflection apply to both regular and diffuse reflection.
