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 12
A periscope uses two plane mirrors placed at 45° angles. Explain how the law of reflection allows the periscope to work.
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.
A periscope uses two plane mirrors placed at 45° angles. Explain how the law of reflection allows the periscope to work.

Fill in the blank: The angle of incidence is measured between the incident ray and the ______.
Fill in the blank: The image formed by a plane mirror is as far ______ the mirror as the object is in front of it.
Fill in the blank: The law of reflection states that the angle of incidence is ______ to the angle of reflection.
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 the same size as the object.
True or False: The image formed by a plane mirror is laterally inverted.
True or False: The laws of reflection apply to both plane and curved mirrors.
