Electromagnetic Waves |
1 |
Mechanical
waves are such waves that need a medium for propagation. |
Electromagnetic
waves are such waves that do not need a medium for propagation. |
2 |
Mechanical
waves are produced by vibratory motion in the respective medium. |
Electromagnetic
waves are produced by a changing of electric and magnetic fields. |
3 |
Sound
waves, water waves, and seismic waves are some examples of mechanical waves |
Radio
waves, microwaves, light waves, U.V waves and infrared waves are some
examples of electromagnetic waves. |
4 |
Mechanical
waves consist of transverse as well as longitudinal waves. |
Electromagnetic
waves are only comprised of a transverse wave in nature. |
5 |
Mechanical
waves cannot travel through the vacuum. |
Electromagnetic
waves travel through the vacuum at the speed of 3 x 108 m/s. |
6 |
All
mechanical waves travel through their media at different speeds depending
upon the physical properties of the respective medium. |
All
electromagnetic waves can travel through transparent media at different
speeds depending upon the refractive index of the respective medium. |
