# How do you explain the electromagnetic spectrum?

## How do you explain the electromagnetic spectrum?

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. Electromagnetic energy passes through space at the speed of light in the form of sinusoidal waves.

What are the 3 ways we describe electromagnetic energy?

Electromagnetic waves can be described by their wavelengths, energy, and frequency. All three of these things describe a different property of light, yet they are related to each other mathematically.

### What is electromagnetic energy in simple words?

Radiation that has both electric and magnetic fields and travels in waves. Electromagnetic radiation can vary in strength from low energy to high energy. It includes radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. Also called EMR.

How do electromagnetic waves carry energy?

In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.

#### Why is it important to understand the electromagnetic spectrum?

It is important because it furnishes information about the composition, the temperature and maybe the mass or relative velocity of the body that emits or absorbs it.

What is the energy of electromagnetic spectrum?

Electromagnetic radiation is a form of energy that propagates as both electrical and magnetic waves traveling in packets of energy called photons. There is a spectrum of electromagnetic radiation with variable wavelengths and frequency, which in turn imparts different characteristics.

## What type of energy makes up the electromagnetic spectrum?

Light waves and other types of energy that radiate (travel out) from where they’re produced are called electromagnetic radiation. Together, they make up what’s known as the electromagnetic spectrum.

What is electromagnetic energy kid definition?

Electromagnetic waves are a form of energy waves that have both an electric and magnetic field. Electromagnetic waves are different from mechanical waves in that they can transmit energy and travel through a vacuum. Electromagnetic waves are classified according to their frequency.

### What is a form of electromagnetic energy?

Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths.

What is the energy of an electromagnetic wave?

ENERGY. An electromagnetic wave can also be described in terms of its energy—in units of measure called electron volts (eV). An electron volt is the amount of kinetic energy needed to move an electron through one volt potential.

#### What is energy carried by electromagnetic waves called?

The energy in electromagnetic waves is sometimes called radiant energy.
