We compare and contrast concave and convex lenses by drawing ray diagrams.

Learn about refraction, ray diagrams and how convex lenses bend light rays with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

The students performed various experiments in remote mode — from physics experiments such as calculating the gravitational constant g using a pendulum to finding the focal length of a convex lens.

Optical Surfaces Ltd has supplied several sets of ultra-high quality plano-convex lenses to the MAX IV Laboratory to function as key focusing elements in diagnosing the beam in their state-of-the-art ...
