Question

Give 3 differences between mechanical wave and radio wave.

Answer 1

Mechanical waves:

• These waves need a material medium for their propagation.
• Mechanical waves are caused by wave amplitude and not by frequency.
• A mechanical wave can be considered a periodic disturbance.

Radio waves:

• These waves do not need a material medium for the propagation.
• Electromagnetic Waves are produced by vibration of the particles.
• A radio or electromagnetic wave is called just a disturbance.
