Students use mirror equations to determine the position and type. Students use mirror equations to determine the position, type, and size of mirror images for curved mirrors mathematically. Optical ...

When light travels from air into glass it slows down because glass is more (optically) dense than air. This change in speed can cause the light to bend at the boundary between the two transparent ...

Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...
