Light: Mirrors and Lenses Self-Assessment Quiz
Try these quick questions after you read the notes. Tap each question to check your answer. They cover the points CBSE asks most often.
A convex mirror always forms an image that is?
(a) enlarged and inverted (b) erect and diminished (c) same size (d) inverted and smaller
Answer: (b) erect and diminished - a convex mirror always spreads light
The law of reflection states that the angle of incidence is?
(a) greater than the angle of reflection (b) less than the angle of reflection (c) equal to the angle of reflection (d) always zero
Answer: (c) equal to the angle of reflection - the two angles match
A lens that is thicker in the middle is a?
(a) concave lens (b) convex lens (c) plane mirror (d) concave mirror
Answer: (b) convex lens - it converges the light passing through it
Which mirror is used in vehicle side-view mirrors?
(a) plane (b) concave (c) convex (d) none
Answer: (c) convex - it gives an erect image and a wider view of traffic behind
A concave lens always forms an image that is?
(a) enlarged (b) inverted (c) erect and diminished (d) same size
Answer: (c) erect and diminished - a concave lens always diverges light
