Question

a convex mirror produces a virtual image when the object is​

Answer 1

Answer:

Virtual images are always formed by convex mirrors and are formed by concave mirrors when the object is placed in front of F. ... Plane mirrors and convex mirrors will always produce an upright image. A concave mirror will only produce an upright image if the object is located in front of the focal point.

Answer 2

A convex mirror will ALWAYS PRODUCE virtual image irrespective of the position of the object in front of the mirror.

• The image characteristics produced by a convex mirror is VIRTUAL, ERECT, DIMINISHED and WITHIN THE FOCAL LENGTH.

Let's assume that the object distance is u, focal length is f and image distance is v :

Applying Mirror Formula :

$\sf \dfrac{1}{f} = \dfrac{1}{v} + \dfrac{1}{u}$

• Value of f is positive, and that of u is negative.

$\implies\sf \dfrac{1}{v} = \dfrac{1}{f} - \dfrac{1}{u}$

$\implies\sf \dfrac{1}{v} = \dfrac{u - f}{uf}$

$\implies\sf v = \dfrac{uf}{u - f}$

• Final value of 'v' will be positive.
