A point object is placed at a distance of 10cm & its real image is...
From a convex lens of focal length 20cm. Determine the position and nature of the image formed.

Using the lens formula, 1/f = 1/v - 1/u, where f is the focal length, v is the image distance, and u is the object distance, we can solve for v.

1/20 = 1/v - 1/10

Simplifying, we get:

1/v = 1/20 + 1/10

1/v = 3/40

v = 40/3 cm

Since the image distance is greater than the object distance, the image is formed on the opposite side of the lens and is therefore a real image.

The magnification is given by the formula, m = -v/u

m = -(40/3)/10

m = -4/3

Since the magnification is negative, the image is inverted.

Therefore, the image is formed at a distance of 40/3 cm from the lens and is inverted.
