Mechanical and Electromagnetic Waves
What is the difference between mechanical and non-mechanical waves?
Low density gaseous medium
Non eleastic medium
Requirement of material medium
Mechanical waves cannot travel through _____.
A mechanical wave needs a medium for propagation.
Information can be passed through particles moving about its fixed positions and influencing the adjacent particles to do the same.
- Configuration of atoms
As a mechanical wave travels through a given medium, it loses its energy to the medium.
Consider the following statements:
Statement 1: No sound can be heard on the surface of the Moon.
Statement 2: Temperature of the surface of the Moon is very high and hence sound waves cannot be produced.
Choose the correct options.
