What are the 7 types of electromagnetic waves and their uses?
Behaviour and uses of electromagnetic wavesRadio waves.
Radio waves are used for communication such as television and radio.
Microwaves are used for cooking food and for satellite communications.
What is the EM spectrum?
The electromagnetic (EM) spectrum is the range of all types of EM radiation. … The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays. You know more about the electromagnetic spectrum than you may think.

Why is it called the electromagnetic spectrum?
The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. Scientists classify them by their frequency or wavelength, going from high to low frequency (short to long wavelength).
Which color has highest and lowest frequencies?
When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
What are the color that have higher energy than red?
Blue lightBlue light has a higher frequency and carries more energy than red light. The wavelengths of light waves are very, very short, just a few 1/100,000ths of an inch.
Which electromagnetic wave has the highest energy?
Gamma raysGamma rays have the highest energies and shortest wavelengths on the electromagnetic spectrum.
Which type of wave travels the fastest?
P-wavesSurface waves travel along the surface. There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
What is the process of electromagnetic radiation?
Electromagnetic radiation is, classically speaking, a wave of electric and magnetic fields propagating at the speed of light c through empty space. In this wave the electric and magnetic fields change their magnitude and direction each second.
What color has lowest frequency?
RedRed has the longest wavelength, the shortest frequency, and the lowest energy.
What are the 7 electromagnetic waves in order?
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
What color has highest frequency?
violetWhen it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
What is another word for electromagnetic radiation?
Electromagnetic radiation synonyms Other common examples of electromagnetic radiation are x-rays, microwaves, and radio waves. A single unit, or quantum, of electromagnetic radiation is called a photon .
Which part of the spectrum can humans see?
visible light spectrumThe visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
What are the types of electromagnetic waves?
Types of Electromagnetic WavesRadio Waves. Radio waves have the longest wavelengths of all the electromagnetic waves. … Microwaves. Microwaves are shorter than radio waves with wavelengths measured in centimeters. … Infrared. Between microwaves and visible light are infrared waves. … Visible light. … Ultraviolet. … X-rays. … Gamma rays. … Activities.
What is electromagnetic radiation in simple words?
Radiation that has both electric and magnetic fields and travels in waves. It comes from natural and man-made sources. 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.
Which wave has the longest period?
The wave with a frequency of 6 Hz has the longest period. Period and frequency have an inverse relationship. thus, the wave with the lowest frequency has the longest period.
Which color has the highest energy?
violetThe frequency of the radiation is proportional to its energy and the wavelength of the radiation is inversely proportional to the energy. Red is the lowest energy visible light and violet is the highest.
