Question

State the types of mirrors used for (i) headlights and (ii) rear view mirrors, in cars and motorcycles. Give reason to justify your answer in each case :

Answer 1

(i) Concave mirror is used in the headlights of vehicles as a reflector. Bulb is placed at the focus of concave mirror so the light rays coming from bulb are collected and after reflection we get a strong beam of light .

(ii) Convex mirror is used as rear view mirrors in vehicles , the other vehicles are always beyond the $2F$ of convex lens so we get a diminished and erect image of other vehicle on lens hence lens gives a larger field of view to us , and we can see more vehicles in lens .
