Question

a ) headlights of a car
b) side / rear view of a vehicle
c) solar furnace
give a reason for each of the following ​

Answer 1

(a) Concave mirror ( Spreads more light)

(b) Convex mirror ( Covers larger area )

(c) Convex mirror ( Focuses light on one region)

Answer 2

Answer:

1. For head lights of a car, we use a concave mirror. The light source is held at the focus of the mirror. On reflection, a strong parallel beam of light emerges.
2. Solar/rear view of vehicle: It is a convex mirror as it gives diminished, virtual and an erect image of the side or rear with wider field of view. A convex mirror enables driver to view much larger area than would be possible with a plane mirror.
3. Solar Furnace: It is a concave mirror. As sun rays after reflection from its surface, get converged at focus with much intense heat.
