Question. What is light?
Answer: Light is a form of energy. It brings the sensation of sight. It is a form of electromagnetic radiation. It also provides us means of communication (fibre-optics).
Question. What is Spherical mirror?
Answer: A reflecting surface which is of the form of a sphere (hollow) in which inner or outer surface is reflecting.
Question. When object is placed at centre of centre of curvature of concave mirror, where is the image formed?
Answer: At C.
Question. What focal length can be assigned to a plane mirror?
Answer: Infinity.
Question. Can any spherical surface act as a reflector?
Answer: Yes, polished surface can be better reflectors.
Question. What is beam?
Answer: A bundle of rays originating from the same source of light in a particular direction is called beam of light.
Question. Explain why a ray of light passing through the centre of curvature of a concave mirror, gets reflected along the same path.
Answer: The ray passing through the centre of curvature incident to the mirror along its normal, so ∠i = ∠r = 0. Therefore, the ray retraces its path.
