What are the first 3 electromagnetic waves?
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light.
What are 10 electromagnetic waves?
11.3 Electromagnetic spectrum (ESADK) EM radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
What are 3 uses for electromagnetic waves?
Uses of Electromagnetic Waves
- Radio waves – radio and television.
- Microwaves – satellite communications and cooking food.
- Infrared – Electrical heaters, cooking food and infrared cameras.
- Visible light – Fibre optic communications.
- Ultraviolet – Energy efficient lamps, sun tanning.
- X-rays – Medical imaging and treatments.
What are electromagnetic waves Class 12?
Electromagnetic waves are those waves in which electric and magnetic field vectors changes sinusoidally and are perpendicular to each other as well as at right angles to the direction of propagation of wave.
What are the three main types of waves?
Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves.
What are some 3 examples of things in everyday life that depend on waves from the EM spectrum?
The differing behaviours of different groups in the electromagnetic spectrum make them suitable for a range of uses.
- Radio waves. Radio waves are used for communication such as television and radio.
- Microwaves.
- Infrared.
- Visible light.
- Ultraviolet radiation.
What are the types of electromagnetic waves?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
What are three examples of electromagnetic waves?
Electromagnetic waves are waves that can travel through a vacuum (empty space). They don’t need a medium or matter. They travel through electrical and magnetic fields that are generated by charged particles. Examples of electromagnetic waves include light, microwaves, radio waves, and X-rays.
What are electromagnetic waves harmful?
Generally, electromagnetic waves, which have higher energy, are more dangerous than those with lower energies. However, to understand which radiation is more harmful, and why it is harmful, we have to know how it transfers energy as it passes through matter.
How are waves used in everyday life?
Radio waves are used every day in our lives, as they are used to broadcast everything that you hear on the radio and see on your television. They have the lowest frequency and the highest wavelength of the electromagnetic spectrum, and are the least potentially dangerous.
What are some examples of EM waves?
Electromagnetic waves can be split into a range of frequencies. This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.
