3 cards from this section. Quick, good the night before a test.
Name the two main types of lenses.
Think about how they manipulate light.
What happens to light rays passing through a convex lens?
Focus on the term 'converge'.
What is a convex lens used for?
Think about how the rays behave.
Concave lenses are thicker in the middle than at the edges.
Consider the shape of the lens.
An object is placed 15 cm from a concave lens with a focal length of -5 cm. Calculate the image distance and describe the image.
Remember to apply the sign convention for concave lenses.
If a convex lens has a focal length of 20 cm and is used to project an image of an object located at a distance of 30 cm from the lens, find the image distance and determine the nature of the image.
Check how different distances affect the image's nature.
