Question

A difference between mechanical and electromagnetic waves is

a. Only mechanical waves can measure frequency

b. Only electromagnetic
waves travel through gas particles

c. Only electromagnetic waves travel
through space

d. Only mechanical waves include light

Answer 1

Answer:

c. Only electromagnetic waves travel  through space

Explanation:

Electromagnetic waves are the only waves that travels through space or vacuum.

These waves do not require any material medium for their propagation as the case may be.

• Mechanical waves requires a material medium before they can be propagated.
• But mechanical waves do not require any medium. They readily move through space without any attenuation.
• This is the salient difference between electromagnetic and mechanical waves.
