Generation of Waves

• The generation of waves requires a source of oscillations.

• Mechanical waves require the disturbance of a medium, which causes particle vibrations within than medium.

• For example, striking a drum cymbal causes it to oscillate, which disturbs the surrounding air, transmitting a sound wave.

Mechanical waves, such as sound waves, require the disturbance of a medium.

• Electromagnetic waves require a source that generates electromagnetic oscillations.

• For example, radio transmitters are electronic devices that produce radio waves by oscillating electrons in an antenna.
