What is the difference between mechanical waves and electromagnetic waves

Asked by admin @ in Physics viewed by 324 People

What is the difference between a mechanical wave and an electromagnetic wave? A mechanical wave travels through empty space, while an electromagnetic wave travels through matter. A mechanical wave has a short wavelength, while all electromagnetic waves have long wavelengths. A mechanical wave has a high frequency, while all electromagnetic waves have low frequencies. A mechanical wave travels through matter, while an electromagnetic wave travels through empty space.

Answer: The correct answer is "A mechanical wave travels through matter, while an electromagnetic wave travels through empty space".

Explanation:

The difference between a mechanical wave and an electromagnetic wave are as follows:

Electromagnetic waves are produced by the vibrations of the charged particles while the mechanical waves are caused by the wave amplitude.

Electromagnetic wave does not need medium while the mechanical wave need medium to travel. Mechanical wave can travel in solid, liquid and gas. Electromagnetic wave travels in vacuum.

Therefore, a mechanical wave travels through matter, while an electromagnetic wave travels through empty space.
