Question

An object of height 5 cm is placed at
distance
of
10cm from a convex mirror of radius of
op
curvature 30 cm
Find the nature position and height
the
image​

Answer 1

Answer:

15

Explanation:

According to the given criteria,

Let height of the image be hi and

Height of the object, ho=5cm

Object distance, u=−10cm

Radius of curvature, R=−30cm

We know, focal length, f=2R=230=−15cm

Now applying mirror formula, we get

f1=v1+u1⟹v1=f1−u1⟹v1=−151−−101⟹v1=150−10+15=15
