Practice Reflection of Light MCQ questions with answers to strengthen your understanding of this important Physics topic. This page includes useful practice questions, previous year questions, correct answers, and explanations to help you prepare for Railway Recruitment Board examinations.
Reflection of light occurs when light rays strike a surface and return to the same medium. Important concepts in this chapter include the laws of reflection, reflection from plane mirrors, image formation, and reflection from spherical mirrors. Understanding these concepts will help you solve conceptual and numerical questions in competitive examinations.

21
An object is 20 cm in front of a concave mirror of focal length 10 cm. What is the correct signed image distance?
RRB Group-D
13/08/2026 (9:00 AM - 10:30 AM)
2026
✓ Answer:A-20 cm
With u = -20 cm and f = -10 cm, 1/v = -1/10 + 1/20 = -1/20, so v = -20 cm.
22
Which scenario best illustrates use of a convex mirror based on the nature of its image?

✓ Answer:CA shopkeeper uses it to monitor a wide area inside a store
Convex mirrors provide a wide field of view and form erect, virtual, diminished images, making them useful for surveillance.
23
A convex mirror monitors a hallway. As a person stands at different distances, what remains true of the images?
RRB Group-D
17/08/2026 (4:30 PM - 6:00 PM)
2026
✓ Answer:AAlways diminished and virtual
For real objects in front of a convex mirror, images are always virtual, erect and diminished.
24
If an image is formed three times the size of the object and is inverted, what is the possible position of the object with respect to a concave mirror of focal length 10 cm?
RRB Group-D
17/08/2026 (12:45 PM - 2:15 PM)
2026
✓ Answer:AObject placed 13.3 cm from the mirror
Using f = -10 cm and m = -v/u = -3 gives v = 3u. Then 1/f = 1/u + 1/(3u), so u = 4f/3 = -13.33 cm. The object is 13.3 cm in front of the mirror.
25
A small candle is 18 cm from a concave mirror of focal length 6 cm. What are the image's nature and position?
RRB Group-D
25/08/2026 (12:45 PM - 2:15 PM)
2026
✓ Answer:BReal, 9 cm in front of the mirror
With u = -18 cm and f = -6 cm, 1/v = -1/6 + 1/18 = -1/9. Thus v = -9 cm: a real image in front of the mirror.
26
A student places an object 15 cm in front of a concave mirror of focal length 10 cm. If the image formed is real, what is the magnification produced by the mirror?
RRB Group-D
06/08/2026 (12:45 PM - 2:15 PM)
2026
✓ Answer:A-2
With u = -15 cm and f = -10 cm, 1/v = 1/f - 1/u = -1/30, giving v = -30 cm. Magnification m = -v/u = -2.
27
An image formed by a mirror is inverted and smaller than the object. What type of magnification is observed?
RRB Group-D
21/08/2026 (12:45 PM - 2:15 PM)
2026
✓ Answer:ALess than one and negative
An inverted image has negative magnification. A diminished image has magnitude less than one, so -1 < m < 0.
28
A dentist uses a concave mirror of focal length 20 cm to examine a patient's tooth. If the tooth is placed 5 cm from the mirror, what is the magnification produced?
RRB Group-D
21/08/2026 (9:00 AM - 10:30 AM)
2026
✓ Answer:B1.33
With f = -20 cm and u = -5 cm, 1/v = -1/20 + 1/5 = 3/20. Thus v = 20/3 cm and m = -v/u = 4/3 ≈ 1.33. The image is virtual and erect.
29
A ray passing through the principal focus of a concave mirror will, after reflection:

14/08/2026 (12:45 PM - 2:15 PM)
2026
✓ Answer:DEmerge parallel to the principal axis
By reversibility of light, a ray through the principal focus reflects parallel to the principal axis.
30
A traffic surveillance camera uses a convex mirror with a radius of curvature of 2 m. Where will the image of a car located 3 m from the mirror appear?
RRB Group-D
14/08/2026 (12:45 PM - 2:15 PM)
2026
✓ Answer:D0.75 m behind the mirror
For the convex mirror, f = R/2 = +1 m and u = -3 m. Hence 1/v = 1 - (-1/3) = 4/3, so v = +0.75 m, behind the mirror.
