Examples of transverse waves include:

• ripples on the surface of water.
• vibrations in a guitar string.
• a Mexican wave in a sports stadium.
• electromagnetic waves – eg light waves, microwaves, radio waves.

Some basic properties of light :

• Reflection of light.
• Refraction of light.
• Diffraction of light.

All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference,

and all waves have a wavelength, frequency, speed and amplitude.
