Ripples on water and light waves are similar because both?
have the same frequency
can be refracted and diffracted
are longitudinal waves
have the same velocity
توضیح
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.
