In other words, we split up the electromagnetic spectrum based on frequency. Visible light, for example, ranges from violet to red. … Electromagnetic waves that are of higher energy than visible light (higher frequency, shorter wavelength) include ultraviolet light, X-rays, and gamma rays.
What are 5 examples of electromagnetic waves?
- Radio Waves.
- TV waves.
- Radar waves.
- Heat (infrared radiation)
- Ultraviolet Light (This is what causes Sunburns)
- X-rays (Just like the kind you get at the doctor’s office)
- Short waves.
What kind of wave is red light?

What is one example of an electromagnetic wave?
Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.
How light is electromagnetic wave?
As light is produced by the acceleration of charged particles & from law of electromagnetism that states that: an accelerated charge produce electromagnetic wave,light is an electromagnetic wave. Actually light is the transfer of energy from one part of electromagnetic field to other.
What are 3 examples of electromagnetic waves?
Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength.
What are the 7 types of electromagnetic radiation?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
Is Violet faster than red?
Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top. This is because what is called the index of refraction, (the ratio of the speed of light in a vacuum to the speed of light in a material), is increased for the slower moving waves (i.e. violet).
Is blue or red light faster?
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.
What is the frequency of red?
What is an example of a light wave?
Visible Light Waves. RADIO WAVES | MICROWAVES | INFRARED | VISIBLE LIGHT | ULTRAVIOLET | X-RAYS | GAMMA RAYS.
What are the types of wave?
Different types of waves have a different set of characteristics. Based on the orientation of particle motion and direction of energy, there are three categories: Mechanical waves.
- Radio waves.
- Ultraviolet waves.
Why electromagnetic wave can travel in vacuum?
An EM wave can travel without a material medium—that is, in a vacuum or space empty of matter—and does not lose energy as it moves. In theory, an EM wave can travel forever. Because they do not need a medium, EM waves can pass through outer space, which is a near vacuum.
How do you detect electromagnetic waves?
To detect the electric fields, use a conducting rod. The fields cause charges (generally electrons) to accelerate back and forth on the rod, creating a potential difference that oscillates at the frequency of the EM wave and with an amplitude proportional to the amplitude of the wave.
Why light is called an electromagnetic wave?
The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. … If it has low frequency, it has less energy and could be a TV or radio wave. All EM energy waves travel at the speed of light. No matter what their frequency or wavelength, they always move at the same speed.
Why do we say light is an electromagnetic wave?
We say that light is an electromagnetic wave because light is an oscillation of electric and magnetic fields. higher energy and shorter wavelength than red light.
