What this chapter covers
Class 8 Science Chapter 10 'Light: Mirrors and Lenses' from NCERT Curiosity studies reflection and refraction qualitatively, with one quantitative tool: the law of reflection (angle of incidence equals angle of reflection). Students explore plane, concave and convex mirrors and convex and concave lenses, see how images form, and learn the basic ray diagrams that explain dispersion, periscopes and the human eye.
Key topics in this chapter
- Reflection — law of reflection
- Plane, concave and convex mirrors
- Refraction through glass and lenses
- Image formation by convex/concave lenses
- Dispersion of white light

The angle of incidence is measured between the incident ray and the:
(a) Mirror surface
(b) Reflected ray
(c) Normal to the mirror at the point of incidence
(d) Edge of the mirror
Answer: Normal to the mirror at the point of incidence

State the two laws of reflection.
Answer: • Angle of incidence = angle of reflection.
• The incident ray, the normal at the point of incidence, and the reflected ray all lie in the same plane.
• Both laws apply to all kinds of mirrors — plane, concave and convex.

A light ray strikes a mirror at 40° to the normal. (i) What is the angle of reflection (with the normal)? (ii) What angle does the reflected ray make with the MIRROR?
Answer: • (i) Angle of reflection = angle of incidence = 40°.
• (ii) Angle with mirror = 90° − 40° = 50°.
