Question

An object is placed at a distance of 20cm in front of a convex mirror with focal

length 20cm. Its image distance is…​

Answer 1

Answer:

Given, f=20cm,u=−20cm,v=?

As, 1/f=1/v +1/u

1/v=1/f−1/u

1/v=1/20+1/20

1/v=2/20

v=10cm

So, the distance of the image from the pole of the mirror is 10cm.

I hope this helps uh dude.

Answer 2

Answer:

V=10cm

Explanation:

1/f=1/v+1/u

1/v=1/f-1/u

1/v=1/20+1/20

1/v=2/20

1/v= 1/10

V=10cm
