Quick Answer: What Are The 7 Electromagnetic Waves And Their Uses?

What are the types of electromagnetic waves and their uses?

Types of Electromagnetic WavesRadio Waves.

Radio waves have the longest wavelengths of all the electromagnetic waves.


Microwaves are shorter than radio waves with wavelengths measured in centimeters.


Between microwaves and visible light are infrared waves.

Visible light.



Gamma rays.


What are the 2 types of radiation?

There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.

What color is the most powerful?

RedRed is the most powerful color amongst all. It has a tendency to stimulate mind and attract attention.

Which has higher frequency Red or Green?

Fast! Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy. Blue light has higher frequency, shorter wavelength and more energy….Visible Spectrum.ColorWavelength Range (nm)Red620–750Orange590–620Yellow570–590Green495–5702 more rows

How do humans use electromagnetic waves?

Examples of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. … Microwaves are used to cook your food. Infrared waves are used in remote controls and are emitted from all warm objects, allowing them to be used to create heat-sensitive cameras.

What are the 7 types of electromagnetic waves and their uses?

Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon.Radio Waves: Instant Communication. … Microwaves: Data and Heat. … Infrared Waves: Invisible Heat. … Visible Light Rays. … Ultraviolet Waves: Energetic Light. … X-rays: Penetrating Radiation. … Gamma Rays: Nuclear Energy.

What devices use electromagnetic waves?

Electromagnetic waves are ubiquitous in nature (i.e., light) and used in modern technology—AM and FM radio, cordless and cellular phones, garage door openers, wireless networks, radar, microwave ovens, etc. These and many more such devices use electromagnetic waves to transmit data and signals.

What is the least dangerous radiation?

Ionizing radiation comes in three flavors: alpha particles, beta particles and gamma rays. Alpha particles are the least dangerous in terms of external exposure. Each particle contains a pair of neutrons and a pair of protons.

What type of electromagnetic wave is texting?

Radio WavesTexting uses Radio Waves which are the lowest-frequency waves in the EM spectrum. Radio Waves are used to carry other signals to recievers that subsequently translates these signals to usable information.

What are the uses of the electromagnetic spectrum?

Astronomers use the entire electromagnetic spectrum to observe a variety of things. Radio waves and microwaves – the longest wavelengths and lowest energies of light – are used to peer inside dense interstellar clouds and track the motion of cold, dark gas.

What are the 7 types of radiation?

The different types of electromagnetic radiation shown in the electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet radiation, X-rays, and gamma rays.

What color has highest frequency?

b. Which color of the visible light spectrum has the greatest wavelength? a. Violet waves have the highest frequencies.

What is the most dangerous type of radiation?

Alpha, beta and gamma radiation alpha radiation is the most dangerous because it is easily absorbed by cells. beta and gamma radiation are not as dangerous because they are less likely to be absorbed by a cell and will usually just pass right through it.

What are the three major types of radiation?

The three most common types of radiation are alpha particles, beta particles, and gamma rays.

What are 2 examples of waves we can see?

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.

What are some examples of electromagnetic waves in your daily life?

In everyday life we encounter radio, microwaves, infrared, ultraviolet, and visible light waves. We usually don’t experience X-rays, and very rarely gamma rays. Radio waves come from communication devices as well as interstellar radiation. Microwaves typically would be found in a microwave.

What kind of radiation is harmful?

Gamma rays are often considered the most dangerous type of radiation to living matter. Unlike alpha and beta particles, which are charged particles, gamma rays are instead forms of energy.

Which is the most powerful radiation?

gamma raysSo what are gamma rays? Gamma rays are the strongest from of radiation. This is what makes nuclear radiation so dangerous. This high energy form of radiation can damage human tissue and cause mutations.

What are the benefits of using electromagnetic waves?

increases the possibility of domestic exposure to magnet- ic fields. Nevertheless, electromagnetic fields can also be used for the treatment of different diseas- es (e.g., cancer, kidney stones, gallstones, brain, liver etc.)
