What makes up the electromagnetic spectrum?

The entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. …

What are the 7 parts of the electromagnetic spectrum?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

What two things make up the electromagnetic spectrum?

The light we can see is only one part of all the electrical and magnetic energy buzzing around our world. Radio waves, X rays, gamma rays, and microwaves work in a very similar way. All together, this energy is called the electromagnetic spectrum.

What determines the electromagnetic spectrum?

The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.

What is the electromagnetic spectrum in simple terms?

Definition: The electromagnetic spectrum is the entire range of wavelengths of all known electromagnetic radiations. It includes: Gamma rays have the smallest wavelengths and highest frequencies known. They are high energy waves capable of travelling long distances through air and are the most penetrating waves.

What produces an electromagnetic wave?

Electromagnetic waves are produced whenever electric charges are accelerated. This makes it possible to produce electromagnetic waves by letting an alternating current flow through a wire, an antenna. The frequency of the waves created in this way equals the frequency of the alternating current.

What are 4 types of waves?

Types of Waves – Mechanical, Electromagnetic, Matter Waves & Their Types.

What is it that waves are made up of?

Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin.

What is the major source of EM waves on Earth?

The most important source of electromagnetic waves on Earth is the sun. Electromagnetic waves travel from the sun to Earth across space and provide virtually all the energy that supports life on our planet.

What do parts of electromagnetic spectrum have in common?

One common behaviour is that they all travel at the same speed in a vacuum. All of these electromagnetic waves (whether radio, visible or gamma) travel at the same speed. They all travel at the ‘speed of light’ through a vacuum, that is at 3 × 10 8 m s1.

How do electromagnetic waves work?

Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component. An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbol c).
