Question

Find the focal length of a convex mirror whose radius of curvature is
32 cm.
A concave mirror produces three times magnified (enlarged) real image
of an object placed at 10 cm in front of it. Where is the image located?
2.​

Answer 1

Explanation:

the focal length of convex mirror is 16

Answer 2

1.Radius of curvature =32

we know,

f=R/2

=32/2

=16cm

2. Given,

m=-3

u=-10cm

we know,

m=v/u

-3=v/-10

v=(-3)×(-10)

v=30cm

Therefore, image will formed at 30cm.
