Question
Distinguish between mechanical and electromagnetic waves.
✓
Answer
| Electromagnetic waves | Mechanical waves |
| 1. They can travel in vacuum. | 1. They cannot travel in vacuum. They need a materia I medium for their propagation. |
| 2. These are formed by the periodic vibrations of mutually perpendicular electric and magnetic field in a plane normal to the direction of wave propagation. | 2. These are formed by the vibrations of the medium particles about their mean positions. These vibrations can be along the direction of propagation of wave or perpendicular to it.. |
| 3. These are traverse in nature. | 3. These waves can be transverse as well as IonqitudnaI. |
