Question

Which of the following statements correctly describes a difference between mechanical waves and electromagnetic waves?

Answer 1

Answer:

The correct answer is Mechanical waves travel only through a medium, while electromagnetic waves can also travel through a vacuum.

Hope this helps!

Answer 2

Answer: The main difference between mechanical waves and electromagnetic waves is propagation medium. Mechanical waves require medium for propagation whereas electromagnetic waves do not require medium for propagation.

Explanation:

• MECHANICAL WAVES

Mechanical waves are those waves which

• cannot travel in vacuum.
• Require medium to travel.
• Can transfer only in the presence of medium.

• ELECTROMAGNETIC WAVES

Electromagnetic waves are those waves which

• can travel in vacuum.
• do not require material support for propagation
• These are due to the electric field and magnetic field.
