The magnification of the lens of -0.5.
Answers
Answer: The magnification is the relationship in size between an object and its image. It's proportional to the distance of each from the lens, which is given by the formulae: 1/u + 1/v = 1/f where u is the object distance, v is the image distance, and f is the focal length. The magnification is then v/u.
what we have to answer
Explanation: Problem:
A object is placed at 30 cm on the principle axis of the convex lens from the lens and an image is formed 60 cm from the lens. If focal length of the lens is 20 cm then calculate the magnification.
Solution:
Given : u=−30 cmThe image is formed behind the lens as the object distance is greater than the focal length of the lens.⟹ v=+60 cm∴ Magnification m=
u
−v
=
−30
−(60)
=2.0
