Question

Which of these is one way that mechanical waves differ from electromagnetic waves?

Question 4 options:

Mechanical waves require energy and electromagnetic waves do not.


Mechanical waves require a medium and electromagnetic waves do not.


Electromagnetic waves require a medium and mechanical waves do not.


Mechanical waves transmit matter and electromagnetic waves transmit energy.

Answer 1

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Mechanical waves require a medium and electromagnetic waves do not.

Hope this helps :)

Answer 2

Mechanical waves require a medium and electromagnetic waves do not.

Step-by-step explanation:

Electromagnetic waves are essentially a combination of electric and magnetic fields produced by the motion of charged particles. They do not require a medium to travel and can simply propagate through space. For example, light waves are electromagnetic waves

Mechanical waves are energy waves that are produced by inducing a certain disturbance in a medium. These waves require a medium to propagate and cannot travel in empty space. For example, sound waves are mechanical waves.
