1.	A S cm tall object is placed perpendicular to the principal axis of a convex lens of locallength 20 cm. The distance of the object from the lens is 30 cm. Determine position,and size of the image.
Answer» Explanation: given , f=20cm v=30cm H'= S cm object DISTANCE = -60CM ( using 1/f = 1/v- 1/u)

A S cm tall object is placed perpendicular to the principal axis of a convex lens of locallength 20 cm. The distance of the object from the lens is 30 cm. Determine position,and size of the image.

Answer»

Explanation:

given ,

f=20cm

v=30cm

H'= S cm

object DISTANCE = -60CM ( using 1/f = 1/v- 1/u)
