A concave mirror produces 3 times magnified real image of an object which is placed at 10 cm in front. The image is at 39 cm front of the mirror

It is given that, Magnification m= -3 (-ve as image is real)

Distance of object u= – 10 cm (-ve as it is on the left side of the mirror)

We can use the formula. From the formula of magnification, m = -v/u

We get, v = – u x m

Substituting the values = -(-10) x (-3)

= -30 cm.

Characteristics of Concave mirror

We have mentioned a few important points related to the Characteristics of Concave mirrors.

Light converges at the point where it strikes and is reflected back from the reflecting surface of the concave mirror. Hence it is also known as a converging mirror.
When a concave mirror is placed very close to an object, a magnified, upright virtual image is obtained.
However, if we increase the distance between the object and the mirror, then the size of the image decreases, and a real and inverted image is formed.
The image formed by a concave mirror can be small or large and can be real or virtual.

Concave lenses are used to cure short-sightedness sight. Apart from this, you can also use this mirror in other works also.
