what are the dangers of electromagnetic spectrum?
46008
The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them.

Large doses of radio waves are believed to cause cancer, leukaemia and other disorders. Some people claim that the very low frequency field from overhead power cables near their homes has affected their health, although this has not been reliably proven.

Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths.

Scientists call this ionizing radiation. In general, the shorter the wavelength, the greater the danger to living things. Although longer wavelengths also have their hazards, very short wavelengths, such as X-rays and gamma rays, can easily damage living tissue.

Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies.

Starting with the most obviously dangerous, gamma rays are the highest frequency and most energetic form of light. They penetrate the human body and cause radiation poisoning after nuclear events like melt downs. Very harmful.

The EM spectrum. Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz.

Examples of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. ... And gamma rays can be used to kill living organisms, sterilize medical equipment, treat cancer, and take images using radioactive tracers.

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.

Answer Expert Verified. Electricity is NOT a part of electromagnetic spectrum. An electromagnetic spectrum contains electromagnetic radiations arranged according to frequencies and wavelength.
931825
On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light.
537776
The electromagnetic spectrum is made up of radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays. The full spectrum is shown in Figure 2.
128066
The entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
1078786
Generally, electromagnetic radiation is classified by wavelength into radio wave, microwave, infrared, visible light, ultraviolet, X-rays and gamma rays. The behavior of EM radiation depends on its wavelength.

The Earth is constantly bombarded with electromagnetic radiation, but the atmosphere protects us from the exposure to higher energy waves that can be harmful to life – i.e. X-Ray and Gamma Rays. The Earth's atmosphere reflects, absorbs and scatters electromagnetic radiation.

Electromagnetic Radiation. Electromagnetic radiation is energy that is propagated through free space or through a material medium in the form of electromagnetic waves, such as radio waves, visible light, and gamma rays. The term also refers to the emission and transmission of such radiant energy.
