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 10
Describe lateral inversion with respect to images formed by plane mirrors.
Describe what happens to the direction of a light ray when it strikes a mirror at 0° angle of incidence (i.e., along the normal).
Explain why a mirror appears to reverse left and right but not top and bottom.
Explain why the image in a plane mirror cannot be projected onto a screen.
Explain why you cannot see your image in a sheet of paper even though it reflects light.
If a person moves closer to a plane mirror, what happens to the size of the image?
State one difference between regular and diffuse reflection.
What is the law of reflection?
A periscope uses two plane mirrors placed at what angle to each other? (1) 30° (2) 45° (3) 60° (4) 90°
Which of the following best describes the image formed by a plane mirror? (1) Real, inverted, same size (2) Virtual, erect, same size (3) Real, erect, smaller (4) Virtual, inverted, larger
Which of the following devices uses the principle of reflection? (1) Microscope (2) Periscope (3) Thermometer (4) Barometer
Which of the following is NOT a property of the image formed by a plane mirror? (1) Virtual (2) Erect (3) Same size as object (4) Inverted vertically
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 distance of the image from the mirror is __________ the distance of the object from the mirror.
Fill in the blank: The image formed by a plane mirror is always __________.
Fill in the blank: The image formed by a plane mirror is as far behind the mirror as the object is __________ the mirror.
True or False: The angle of incidence is measured from the surface of the mirror.
True or False: The image formed by a plane mirror is always behind the mirror.
True or False: The image formed by a plane mirror is laterally inverted.
True or False: The law of reflection is valid only for light rays and not for other types of waves.
