Question

(a) What is the difference between the images
formed by a large and a small mirror?
(b) If object is between focus and pole of a
concave mirror, explain image formation with
the help of ray diagram.
(c) Can a convex mirror be used to form real
image for an object? Explain.​

Answer 1

Answer:

a) Large mirrors covers large space as an object so in large mirror you can observe your surroundings whereas small mirror might not be able to cover the whole object.

b) When a parallel beam of light from a far off object falls on a concave mirror, a real, inverted point size image is formed at the point called focus. these rays are assumed to be paraxial, i.e. when incident at points close to the pole of the mirror they do make smaller angles with the principal axis.

c) Convex mirrors can produce real images as well. If the object is virtual, i.e., if the light rays converging at a point behind the plane mirror (or a convex mirror) are reflected to a point on a screen placed in front of the mirror, then a real image will be formed.
