Question

An object is kept at a distance of 30cm from a diverging lens of focal

length 15cm. At what distance the image is formed from the lens? Find

the magnification of the image​

Answer 1

Answer:

Substitute f=−30cm and v=−15cm to find the value of u. Substitute, v=−15cm, u=−30cm and h1=5cm to find the value of h2. Therefore, the object should be placed 30 cm from the optical centre and the size of the image formed is 2.5 cm.
