Convex and concave lenses can both be used to correct defects of vision. The most commonly occurring defects of vision are ‘short sightedness’ and ‘long sightedness’. People who are ...

Learn about and revise lenses and their power, real and virtual images, and ray diagrams with GCSE Bitesize Physics.

We compare and contrast concave and convex lenses by drawing ray diagrams. In this Closer Look segment on Lenses, we compare and contrast concave and convex lenses by drawing ray diagrams and ...

Concave lens formula is used to determine the position and nature of the image formed after a ray of light passes through the concave lens. The formula is known as the lens formula.

Lens is a transparent glass which is bounded by two spherical surfaces. The light rays are refracted after passing through the lens. It is of two types, convex lens and concave lens.
