Question

What are common properties of waves?

Answer 1

1. Waves transfer energy from one place to another without permanent transfer of matter.
2. Waves have wavelength (λ), frequency (f), time period (T) and amplitude.
3. Wave speed is related to frequency and wavelength by:
   v = f λ
4. Waves can undergo reflection, refraction, diffraction and interference.
5. The particles of the medium, if present, only oscillate about their mean positions while the wave travels forward.
