Question
An object is located in front of a convex lens of focal length 40 cm at a distance of 80 cm. The image will be formed ____.
- In the same side as the object
- In the opposite side as the object
- Behind the object
- Is virtual and upright
The correct answer is: In the opposite side as the object
- Here u =-80, f=40
- So v=80 cm
- Hence v is positive so The image will be formed In the opposite side as the object
