What are the 7 types of electromagnetic radiation?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays..
What are the 6 types of electromagnetic radiation?
Generally, electromagnetic radiation is classified by wavelength into radio wave, microwave, infrared, visible light, ultraviolet, X-rays and gamma rays.
How does an electromagnetic wave begin?
An electromagnetic wave begins when an electrically charged particle vibrates. This causes a vibrating electric field, which in turn creates a vibrating magnetic field. The two vibrating fields together form an electromagnetic wave.
Is infrared radiation bad?
Near infrared waves are short and not hot — in fact you cannot even feel them — which is what makes them particularly dangerous to susceptible tissues, such as skin and eyes. Skin exposed to IR provides a warning mechanism against thermal effect in the form of pain. Eyes, on the other hand, may not.
What are the 7 electromagnetic waves and their uses?
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.
What electromagnetic radiation is harmful?
The electric and magnetic forces in EMFs are caused by electromagnetic radiation. There are two main categories of EMFs: Higher-frequency EMFs, which include x-rays and gamma rays. These EMFs are in the ionizing radiation part of the electromagnetic spectrum and can damage DNA or cells directly.
What are the 4 types of electromagnetic radiation?
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 are the 10 types of waves?
Usually, waves are around us, it can be sound waves, radio waves, water waves, sine waves, cosine waves, string waves, slinky waves etc. These are created through disturbance.
How do you detect electromagnetic radiation?
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.
Which type of radiation has the most energy?
Gamma raysGamma rays have the highest energy and shortest wavelength. Then come X-rays, ultraviolet light, visible light, infrared radiation and microwave radiation. Finally, radio waves have the lowest energy and longest wavelength.
What are the 4 main properties of electromagnetic waves?
Every form of electromagnetic radiation, including visible light, oscillates in a periodic fashion with peaks and valleys, and displaying a characteristic amplitude, wavelength, and frequency that defines the direction, energy, and intensity of the radiation.
