When people look into a mirror, they see an image of themselves behind the glass. That image results from light rays encountering the shiny surface and bouncing back, or reflecting, providing a ...

PITTSBURGH (KDKA) -- Without light, we can't have sight. We see objects because of how light interacts with those objects, our eyes pick up that light, and our brains interpret it. This seems rather ...

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 ...

There are different ways to investigate refraction in rectangular blocks. In this required practical activity, it is important to: make, measure and record the angles of incidence accurately using a ...

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 ...
