Cell phone, and wifi is the most dangerous, because of the greed to make money. Brain doctors don't use them because they know of the brain tumor they cause... see Dr. Marcola.com. The FDA is paid off by the big greed Lobbist.

What is more dangerous high frequency radiation or low frequency radiation?
heya. Okay so I had the same question for a sheet i had to do in my physics lesson.The harm done to humans by EM radiation depends on the intensity and wavelength of the radiation.high frequency radiation has more potential to damage human DNA than longer wavelengths (Low frequency). That's why UV radiation tends to promote skin cancer while visible light has no known tendency to do so. Short-wavelength radiation can also carry more energy than long-wavelength radiation of the same intensity.Long-wavelength radiation is more known for its tendency to cause human tissue to heat up, which can cause death more quickly than short-wavelength radiation. Microwave energy is one example of this; fairly high-intensity microwaves are used to heat food in a microwave oven.So really high frequency is more dangerous, such as gamma rays :)source: Is_electromagnetic_radiation_harmful_to_humans
Long wavelength and a low frequency is what type of radiation?
Electromagnetic radiation
Radiation on tranformers?
Very low frequency.
What is the difference between nuclear radiation and heat radiation?
Heat radiation is infrared radiation, which is a relatively low frequency radiation, slightly lower than that of visible light. Nuclear radiation includes a variety of types, including X rays and gamma rays, which are very high frequency radiation, and which are consequently much more dangerous, and can cause radiation sickness. There are also other types of nuclear radiation such as alpha rays, beta rays, and neutrons, all of which are in the form of subatomic particles rather than electromagnetic radiation.
What are the forms of radiation?
Alpha, Beta, Neutron, X-ray, Gamma, Neutron radiation, Electromagnetic radiation, Visible light, Infrared, Microwave, Radio waves, Very low frequency (VLF), Extremely low frequency (ELF), Thermal radiation (heat) and Black body radiation.
Waves with long wavelength low frequency?
yes waves with long wavelengthhave low frequency also low energy.
How does the frequency of radiant energy relate to the absolute temperature of the radiating source?
A low temp source emits low-frequency, long wavelength waves. A medium temp source emits medium frequency, medium wavelength waves. A high temp source emits high frequency, short wavelength waves.
What is low frequency radiation called?
LF-RF or low frequency radio frequencies. This spans frequencies from just below the AM radio band through the shortwave radio bands.
Why does electromagnetic radiation have the lowest energy?
Electromagnetic radiation has a wide range of energies. On the low end, there is ELF, and on the high end there is gamma radiation. It all depends on frequency.
Which type of radiation in the electronmagnetic spectrum is the least energetic?
The electromagnetic spectrum is a continuum. The least energetic type of radiation may be found in what is known as "extremely low frequency" radiation (ELF). This is radiation with a frequency in the range 3-30 Hertz. ELF radiation can penetrate seawater and so is particularly useful for communicating with submarines.
In classical physics how does an atomic oscillator behave when heated in terms of energy emissions?
The oscillator starts at relatively low frequency and emits electromagnetic radiation of relatively low frequency (or long wavelength) and low intensity. As the heating continues, the frequency of oscillation also increases as does the frequency of the emitted radiation and the intensity of the radiation. A graph of intensity vs. wavelength would start high on the left (at short wavelengths) and fall off to the right exponentially to low intensity at long wavelengths. This graph would be at odds with the experimentally established graph of intensity vs. wavelength(which shows low intensity at short wavelengths) because the classical assumption that frequency of oscillation can increase continuously as the oscillators are heated is not correct. Frequency of oscillation can increase only in integral multiples of the fundamenal frequency.
Which type of em spectrum has the highest wavelength?
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
