Question

in a convex lens object distance is 50 cm and focal lenggth is 20 then what is the distance of image

Answer 1

Answer:

Step-by-step explanation:

We can use Gaussian equation for thin lens with Cartesian sign convention . 1/f = 1/v - 1/ u

Here, object distance, u = -30 cm.

Focal length , f= 50 cm.

Image distance, v = ?

Thus, 1/50= 1/v -(-1/u) OR

1/50 - 1/20 = 1/v OR

v= -33.33 cm.

Answer 2

Step-by-step explanation:

v = 33.33 cm. is your answer.
