Question

An object is placed in 5 cm distance from the centre ofa convex lens whose focal length is 10 cm. With the help of ray diagram write the nature and size of the image formed.​

Answer 1

Answer:

object distance = 5 cm

focal length = 10 cm

lens type = convex

by using lens formula

1/V - 1/U = 1/F

1/V = 1/F + 1/U

1/V = 1/10 - 1/5

1/V = 1/10 - 2/10

1/V = -1/10

V = -10 cm
