An object is kept 5 cm in front of a concave mirror of focal length 15 cm. What will be the nature of the image?

Virtual, not magnified

Virtual, magnified

Real, not magnified

Real, magnified

Explanation:

Virtual, magnified

Using v1?+u1?=f1?

∴ v1?+−51?=−151?

? v=+7.5 cm

So image is formed behind the mirror, thus it is virtual.

Magnification m=u−v?=−5−7.5?=1.5

So, magnified image is formed.
