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 ...

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 ...

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

Geometrical optics studies light on a macroscopic scale, treating it as rays that travel in straight lines and change direction through reflection or refraction. Angles are measured from the normal, ...

The questions in this quiz are suitable for GCSE physics students who are studying reflection of waves and refraction of waves. If you struggled with the quiz, don't panic - we've got you! You can ...

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 ...
