Question

v) What is the electromagnetic wave? What are the
differences between electromagnetic wave and mechanical
waves?
​

Answer 1

$\huge{\fbox{\fbox{\red{Definition}}}}$

→Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.They are also perpendicular to the direction of the EM wave.

$\huge{\fbox{\fbox{\red{Their \: Difference}}}}$

→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.

Answer 2

Answer:

Electromagnetic waves are those wave which are related to both electricity and magnetism .

Explanation:

Differences between electromagnetic waves and mechanical waves.

Electromagnetic wave:- Doesn't need a medium to travel.

It is transverse wave.

Example:- sound wave , water wave etc.

Mechanical waves:- Need a medium to travel .

It is Longitudinal wave .

Example:- Light wave.
