Question

What are mechanical waves
&
non mechanical waves​

Answer 1

• Non-mechanical waves are waves that do not require a medium for the transfer of their energy to occur. Electromagnetic waves are the only type of non-mechanical waves. They can travel through the vacuum of space.
• Type of radiation: Range of wavelengths
• Microwave: 0.1 down to 0.001 meters
• Visible light: 700 to 400 nm
• Infrared radiation: 10-3 down to 10-7 meters

Answer 2

Answer:

Non-mechanical waves are waves that do not require a medium for the transfer of their energy to occur. Electromagnetic waves are the only type of non-mechanical waves. They can travel through the vacuum of space.

Explanation:

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.
