VIBRATIONS
WAVES
A wave is a disturbance or vibration which
propagates along a medium or space with transferred energy by one point to
another point, while the medium itself does not propagate.
The classifications of
waves :
A. Based on the medium of
propagation
1. Mechanical wave
A wave that
needs a medium in which the wave propagates.
Examples :
string wave, ocean wave, sound wave, etc.
2. Electromagnetic wave
A wave does
not need any media to propagates.
Examples : light waves,
radio waves, micro waves, X-rays, etc.
