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 ...

At the interface between two facets of an artificial crystal, sound waves can be transmitted in the opposite direction to that expected, and undergo no reflection. Such wave behaviour could have many ...

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 ...

You won’t believe your eyes with this week’s experiment! It is all about light! Light can behave in different ways; it can reflect, refract, or be absorbed. In this experiment, you can teach your kids ...

This exhibition highlights 24 objects from the collection in which light—as substance and subject—is central. Encompassing important practices and movements from the 20th century to the present, these ...
