In this activity, pupils will learn about refraction and reflection, and how they’re different. You only need simple bits of ...

Geometric optics explains how light behaves when it reflects, refracts, and forms images through lenses and mirrors. From total internal reflection in fiber optics to the sparkle of rainbows, these ...

A ripple tank can be used to investigate the frequency close frequencyThe number of waves produced each second. The unit of frequency is hertz (Hz)., wavelength close wavelengthThe length of a single ...

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 ...
