Wave Behaviour | Waves | Physics | FuseSchool

How do waves behave? Badly? In this video we are going to look at how light and sound waves behave. Before we start, you should know that waves can be transverse or longitudinal.

Transmission, reflection, refraction, diffraction, absorption and scattering are all typical wave behaviours.

Reflection is when waves bounce off an object. Sound waves are reflected by hard, flat surfaces and is why we get echoes.

You hear a delay between the original sound and the echo, because the echoed sound waves have to travel twice as far to reach your ears.

Smooth surfaces, like glass and polished metal, reflect light in a regular way, so a reflection can be seen. Like a mirror, or seeing your face in a calm pond.

Transmission is when waves keep travelling in the same direction through an object. Like light through a window.

Absorption and reflection often go hand in hand for light waves.

White light contains each wavelength - so all the colours of visible light. The colour of an object depends on which wavelengths of light it absorbs and which it reflects.

[...]

Sometimes waves depart from the expected path, and spread out in multiple directions. This is known as scattering.
