Answer 1

Answer:

the object is placed at a distance 12 cm from convex lens of focal length 8 cm find its position of the image and nature of the image.

Answer 2

Answer:

Explanation:

Given,

u = -12cm.(For Convex Lens).

f = 8cm.

v = ?

1/f = 1/v - 1/u.

1/8 = 1/v + 1/12.

1/8 - 1/12 = 1/v.

3-2/24 = 1/v.

1/24 = 1/v.

v = 24 cm.

To Find The Nature Of The Image.

v =24(positive).

That Implies, It Is A Real Image.

m = v/u.

24/-12 = -2.

That Implies, Diminished Image.

The Image Is Upright.
