# Why do electromagnetic waves not need a medium?

Contents

The electromagnetic waves are not mechanical waves. There are vibrations of electric vector and magnetic vector in them. These vibrations do not need any particles present in the medium for their propagation. That’s why electromagnetic waves do not require any medium for propagation.

## Why do electromagnetic waves not require a medium for travel quizlet?

Waves travels perpendicular of each other or right angles of each other. … Electromagnetic waves do not require a medium such as air, so they can transfer energy through vacuum, or empty space.

## Do electromagnetic waves need a medium to travel through?

Propagation of an Electromagnetic Wave

Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.

## Do electromagnetic waves need a medium to travel through like mechanical waves do explain why or why not quizlet?

Light from the sun and stars could not travel through space to the Earth if light was a mechanical wave. Outer space is a vacuum so there is no medium for a mechanical wave to travel through. Electromagnetic radiation does not need a medium.

## What is energy that travels in electromagnetic waves and does not require a medium?

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.

## Do you not need a medium?

Waves that don’t require a medium are called electromagnetic waves.

## Do you not need any medium?

Answer: Electromagnetic waves ( e.g. light) do not require any medium.

## Why do waves need a medium?

a medium is required in order for sound waves to transport energy. Mechanical waves require a medium in order to transport energy. Sound, like any mechanical wave, cannot travel through a vacuum.

## Which wave Cannot move without a medium in which to travel?

Electromagnetic Waves – Do not require a physical medium through which to travel. Electromagnetic waves can travel through a vacuum. Examples: Radio waves, visible light, x-rays, etc.

## What type of waves do not require a medium for the wave to travel quizlet?

A form of energy that can move through the vacuum of space. – Mechanical waves require a medium to travel through, while Electromagnetic waves do not.

## Which medium can electromagnetic waves travel through the fastest?

Electromagnetic waves- travel fastest in empty space and slowest in solids.
