- Waves play an important role in our daily life. It is because waves are carrier of energy and information over large distances. Waves require some oscillating or vibrating source. Here we demonstrate the production and propagation of different waves with the help of vibratory motion of objects.
- Basic definition of wave is: A wave is a disturbance in the medium which causes the particles of the medium to undergo vibratory motion about their mean position in equal intervals of time.
Types of Waves:[change | change source]
There are two categories of waves.
1) Mechanical Waves
2) Electromagnetic Waves.
Mechanical Waves:[change | change source]
Waves which require any medium for their propagation are called mechanical waves.
Water waves, sound waves, and waves produced on the string and spring.
Electromagnetic Waves:[change | change source]
Waves which do not require any medium for their propagation are called electromagnetic waves.
Radio waves, television waves, X-rays, heat and light waves are some examples of electromagnetic waves.
