Image Formation by Mirrors 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 Image Formation by Mirrors.
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 8
A 5 cm tall object is placed 15 cm in front of a concave mirror with a focal length of 10 cm. Calculate the image distance.
A person stands 2 meters in front of a plane mirror. What is the distance between the person and his image?
Explain why convex mirrors are preferred as rear-view mirrors in vehicles.
Explain why the image in a plane mirror appears to be laterally inverted.
If an object is placed at infinity in front of a concave mirror, where is the image formed?
If an object is placed at the center of curvature of a concave mirror, where will the image be formed?
If an object is placed at the focus of a concave mirror, where will the image be formed?
If the focal length of a concave mirror is 10 cm, what is its radius of curvature?
If the magnification produced by a mirror is -2, what does the negative sign indicate?
If the object distance (u) is -20 cm and the focal length (f) is -10 cm for a concave mirror, calculate the image distance (v).
Name the type of mirror used as a rear-view mirror in vehicles.
State one difference between real and virtual images.
State the law of reflection.
What is meant by lateral inversion?
What is the mirror formula for spherical mirrors?
What is the nature of the image formed by a plane mirror?
