Question

Focal length of the concave mirror is 8 cm. The object is placed at
16 cm infront of the mirror. Write the position of image and its nature​

Answer 1

Answer:

below the centre of curvature , invert image

Explanation:

since the object is placed at 2f [ ie; f=8cm] the object is in the centre of curvature. so by ray diagrams,u will get the answer

Answer 2

Answer:

Position = At centre of curvature and Nature = Real and Inverted.

Explanation:

Given data :- F = -8cm

U = -16cm

V = ?

Now, by Mirror Formula,

1/F = 1/V + 1/U

1/-8 = 1/V + 1/-16

1/-8 - 1/-16 = 1/V

1/-8 + 1/16 = 1/V

16 - 8/ -128 = 1/V

8/-128 = 1/V

-128/8 = V

-16 = V

I hope it will help you.
