How to Draw a Ray Diagram for a Concave Lens Step 1:Identify the focal length of the concave lens ({eq}f {/eq}) and the distance from the center of the lens ({eq}d {/eq}). Step 2:Draw the object relative to the lens and label the focal length on either side of the lens. ...
Imagine light rays coming into a concave lens and then shooting out in all directions. That's why a concave lens is sometimes called a diverging lens. It makes light rays shoot out (diverge). Concave lenses are used in movie projectors to make light from the film spread out and cover a...
A concave lens is similar to two prisms that are touching at the thinnest point. This creates a lens that is thinner at the center and thicker at the edges — a concave lens. Light is always bent toward the base in a prism. In the case of a concave lens, the thick base is at the...
