The lowest frequency is generally that of radio waves, while the highest frequency is that of gamma rays. And, as you can see, the tendency for wavelength is the reverse, as frequency and wavelength are inversely connected. The higher the frequency, the shorter the wavelength.
Frequency is the number of times something occurs within a given period. For example, the frequency of the bell at a church is about three hundred times per minute. The rate at which cars pass by a window is about one thousand five hundred times per hour. The frequency of visible light is about six times ten to the thirty-threerd power Hz. Infrared radiation has a frequency about one hundred fifty times that of red light.
Wavelength is the distance between two successive maximums or minimums. For example, the wavelength of light from the sun is approximately 250 million km. The wavelength of sound is about 20 million km. In general, wavelengths are much smaller than distances between objects. For example, a grain of sand is about one hundred thousand times smaller than the ocean but makes up half of all particles suspended in water. Raindrops are about 5 million times smaller than a grain of sand but only make up 1% of all particles suspended in air.
Gamma rays are the most energetic, have the shortest wavelengths, and have the highest frequencies. Radio waves, on the other hand, have the lowest energy, the longest wavelengths, and the lowest frequencies of any form of electromagnetic radiation. Thus, radio waves have the narrowest frequency range of all wave types. Gamma rays can cover the greatest distances of any type of wave.
Radio waves have very limited use because they do not carry energy beyond what is given off by their source. This means that radio waves cannot be used to transmit information, only energy. They are useful for short-range communications over small areas such as within a building or between two devices located in close proximity to each other. The wavelength of radio waves is too long to effectively transmit information over large distances compared to other forms of transmission.
Light has many advantages over radio waves for transmitting information over long distances. It does not need to travel through space, so it does not lose energy like radio waves do, and it can be controlled using optics, which make it efficient at switching signals "on" and "off". Light can also carry more information than radio waves per unit length; there are limits to how much data you can transmit via radio waves due to noise issues. However, light needs a physical connection to transmit information, so it cannot cross open spaces such as oceans.
Gamma rays have the most energy, the shortest wavelengths, and the highest frequency. Radio waves, on the other hand, have the smallest energy, longest wavelengths, and lowest frequencies of any form of electromagnetic radiation. An electric signal has both high frequency and low voltage.
The frequency of a wave is the number of times it rises or falls in per second. Waves with high frequencies are called "high-frequency" or "shortwave" waves. Low-frequency waves are called "low-frequency" or "longwave" waves.
High-frequency waves can be used to transmit information over long distances quickly, which is why radar systems use this type of waveform. Low-frequency waves are useful for heating homes and businesses during winter months, when we need heat but don't want to turn on the main power line. These types of systems use low-frequency waves transmitted through copper wires inside buildings. Other low-frequency devices include radio and television receivers, which use the oscillations of antennas to produce signals that can be converted into words and pictures by your television set, and audio speakers that work based on the same principle as radio telescopes - they emit sound waves when current is applied to them.
