Question

A 4.0cm tall object is placed 60cm away from a converging lens of focal length 30 cm. What is the nature and location of the image?

Answer 1

Answer #1

We know that

1 / f = 1 /p + 1 / i

1 / 30 = 1 / 60 + 1 / i

Therefore i = 60 cm

The image is real. 4.0 cm tall, 60cmc on the other side of thelense.
