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.

1
If a convex mirror forms a point-sized image at its focus, where is the object located?

2026
✓ Answer:AAt infinity
For a convex mirror, rays parallel to the principal axis appear to come from the focus behind the mirror. Thus, an object at infinity forms a highly diminished image at the focus.
2
A solar cooker uses a mirror to concentrate sunlight onto a vessel. Which type of mirror is used and what property makes it suitable?

19/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:BA concave mirror because it focuses parallel sunlight to a single point
A concave mirror converges parallel sunlight rays to its focus. Concentrating sunlight at one point produces intense heat, which is why it is useful in a solar cooker.
3
When an object is placed at infinity in front of a convex mirror, what is the nature of the image formed?
RRB JE
19/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:CVirtual and erect
Parallel rays incident on a convex mirror appear to diverge from its principal focus behind the mirror. Therefore the image is virtual, erect and highly diminished.
4
A ball at rest is dropped from the top of a 20 m high building. Calculate the speed with which it hits the ground. (Take g = 10 m/s²)
RRB JE
19/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:D20 m/s
A concave mirror has its reflecting surface curved inward, toward the centre of curvature.
5
A technician needs to connect a new appliance in a domestic circuit to ensure it receives full voltage and can be operated independently. What should the technician do?
RRB JE
20/02/2026 / 9:00 AM - 10:30 AM
2026
✓ Answer:BConnect the appliance in parallel with existing appliances
Using the Cartesian sign convention for mirrors, distances measured perpendicular to the principal axis below the principal axis are taken as negative.
6
A security mirror in a store is required to provide a wide field of view and always form diminished, upright images regardless of the position of objects. Which type of mirror and principle should be used for its design?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:DConvex mirror using the mirror formula for virtual, diminished images
A convex mirror always forms a virtual, erect and diminished image and provides a wide field of view, making it suitable as a security mirror.
7
A dentist uses a mirror to obtain a large image of a patient’s tooth. Which mirror should the dentist use and why?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:BConcave mirror, because it gives a magnified image
For a convex lens, the principal focus lies on the side opposite the incident light. Under the Cartesian sign convention this focal length is positive.
8
How do rays parallel to the principal axis behave after reflection from a convex mirror?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:BThey appear to diverge from a point on the principal axis.
The SI base unit of length is metre (m), which is the standard unit used to measure distance and displacement.
9
When using the sign convention for spherical mirrors, which direction along the principal axis is considered positive?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:ATo the right of the origin (along + x-axis)
Most solids expand when heated because increased thermal energy causes their particles to vibrate more strongly and their average separation to increase.
10
A convex mirror has a radius of curvature of 50 cm. A parallel beam strikes the mirror. At what distance from the pole does the reflected beam appear to diverge?
RRB Group-D
09/08/2026 (12:45 PM - 2:15 PM)
2026
✓ Answer:A25 cm behind the mirror
The reflected rays appear to diverge from the virtual focus. Its distance is f = R/2 = 25 cm behind the mirror.
