Science
Name the type of mirror used in the following situations.
(a) Headlights of a car
(b) Side/rear-view mirror of a vehicle
(c) Solar furnace
Support your answer with a reason.
Answer
(a) Concave mirrors because they produce powerful parallel beam of light when the light source is placed at its principal focus.
(b) Convex Mirror because they always give an erect image with a wider field of view as they are curved outward, enabling the driver to view much larger area than would be possible with a plane mirror.
(c) Concave Mirror because it concentrates the parallel rays of the sun at a principal focus.

We wish to obtain an erect image of an object, using a concave mirror of focal length 15 cm. What should be the range of distance of the object from the mirror? What is the nature of the image? Is the image larger or smaller than the object? Draw a ray diagram to show the image formation in this case.
