How much of the worlds population is exposed to unhealthy air?
0-0
What is the sentence of the frequency?
I would very much like to see you with greater frequency. What frequency will you be on? I can switch to another radio station by adjusting the frequency of my radio receiver.
What is an absolute comparison?
In Epidemiology Absolute comparison indicates how much greater is the disease frequency in the exposed group , compared with non-exposed.
Which has a higher frequency gamma rays or radio rays?
Gamma rays have a higher frequency than radio waves. Gamma rays have the shortest wavelength and highest frequency in the electromagnetic spectrum, while radio waves have the longest wavelength and lowest frequency.
How does sputnik affect the people around it?
Not much. It wasn't radioactive, it couldn't do much but beep on a radio frequency.
Do am radio waves have a lower frequency then ultra violet radiation?
Radio waves and ultraviolet waves are the same physical phenomenon.The difference is that radio waves have a much greater wavelength.(That's equivalent to saying that they have a much lower frequency.)
Does visible light have a higher frequency then radio waves?
Yes, visible light has a higher frequency than radio waves. Visible light falls within the range of frequencies between infrared and ultraviolet light, while radio waves have much lower frequencies.
The main difference between a radio wave and a light wave is?
The difference between a radio wave and a x-ray is the fact that x-rays have a much higher frequency. Since higher frequency means more energy in electromagnetic waves, x-rays can be used for purposes such as taking photos of things inside the body. Radio waves are at a lower frequency and have a much longer wavelength. They are used in radio, television, and communication.
What type of electromagnetic wave is used for television?
Television signals primarily rely on electromagnetic waves within the radio frequency range, specifically UHF (Ultra High Frequency) and VHF (Very High Frequency) bands. These waves are used to transmit audio and video information to TV antennas for reception by television sets.
What is an rfid chip?
The RFID chip is a Radio Frequency IDentification chip. When it receives a radio wave in the right frequency range, it sends back a characteristic radio signal which allows it to be specifically identified, much like a bar code would when optically scanned.
Do radio waves have a high frequency?
Because the X-ray has a shorter wavelength (kuch shorter!) the energy is much greater in an X-ray. Therefore with a bigger energy, E = hv would calculate a higher frequency for x rays. As the eregy of a wave increases, so goes the frequency. Actually, it probably should be stated the other way, but I still have answered your question
How does the frequency of radio waves compare with the frequency of visible light?
The radio wave part of the spectrum is very wide. The extreme ends are, roughly,15km ( used for communicating with submerged submarines)1 mm ( used for research, and possibly for radar)The visible spectrum covers only a 2:1 range of wavelengths. It is centred on the colour yellow, with a wavelength ~= 700nm.The very shortest of the radio waves is about 1000 times as long as yellow light.
