Copy and complete the diagram below to show what happens to the rays of light when they pass through the concave lens:
With the help of a diagram, explain why the image of an object viewed through a concave lens appears smaller and closer than the object.
When an object is placed 10 cm in front of lens A, the image is real, inverted, magnified and formed at a great distance. When the same object is placed 10 cm in front of lens B, the image formed is real, inverted and same size as the object.
What is the focal length of lens B?
A concave lens of focal length 15 cm forms an image 10 cm from the lens. How far is the object placed from the lens? Draw the ray diagram.
