In the electromagnetic spectrum, the longest waves are created by lightning strikes. These extend down to low audio frequencies - 10kHz and below. Natural phenomenon called Whistlers and Sferics demonstrate this. These have been picked up by satellites near Jupiter, thus proving that there is lightning on Jupiter.
These Very Low Frequencies are also used for communicating with submarines, for the penetration of an E-M wave into seawater is proportional to wavelength. Naturally the bandwidth is very low, so only pre-programmed messages may be sent, but that is compatible with the security levels desired.
These communications are usually below 30kHz, and several transmitter stations are used. There is a list of such transmitters in Wikipedia under VLF. Several of these radiate powers of a few megawatts to counter losses in the ocean.
What else can I help you with?
Does your hand emit long or short wave radiation and how do you know?
Long wave radiation in the form of infrared waves. These can be seen with an infrared camera.
Does the radiation emitted by earth's surface have longer or shorter wavelengths compared to solar radiation?
The radiation emitted by Earth's surface has longer wavelengths compared to solar radiation. Earth emits long-wave radiation in the infrared range, while solar radiation consists of shorter-wave radiation in the visible and ultraviolet ranges.
What type of radiation from Earth is the long-wave radiation absorbed by greenhouse gases?
The long-wave radiation absorbed by greenhouse gases is primarily in the form of infrared radiation. After the Earth's surface absorbs solar energy, it re-emits this energy as infrared radiation, which has longer wavelengths compared to the short-wave radiation from the sun. Greenhouse gases in the atmosphere, such as carbon dioxide and methane, absorb and re-radiate this infrared radiation, contributing to the greenhouse effect and warming the planet.
What is the heat budget?
Is the balance between incoming short wave solar radiation (infra) and outgoing long wave solar radiation (TERESTRIAL) to avoid over cooling and overheating of the atmosphere.
What is long-wave electromagnetic radiations used in special telescopes?
Long-wave electromagnetic radiation used in special telescopes includes infrared radiation and submillimeter radiation. These telescopes are designed to detect and study objects that emit or reflect these longer wavelengths of light, allowing astronomers to observe phenomena such as cool stars, cosmic dust, and molecular clouds.
What is the heating effect of a medium that is transparent to the short wave length radiation of sunlight but opaque to the long wave terrestrial radiation?
ultraviolet rays
What is the primary function of the clear glass of the greenhouse?
the glass allows short wave lengths of radiation to enter, but reduces the amount of long-wave length radiation that escapes
What are the three types electromagnetic spectrums?
-- Long-wave radiation -- Medium-wave radiation -- Short-wave radiation
What is electromagnatic?
it is a range of different radiation with different wave length
Is long wave heat radiation given off by the earth when the earth absorbs short wave radiation?
Yes, long-wave heat radiation is given off by the Earth as it absorbs short-wave radiation from the Sun. This process is known as the Earth's energy balance, where incoming solar radiation is absorbed by the Earth's surface and later re-emitted as long-wave heat radiation.
Does your hand emit long or short wave radiation and how do you know?
Long wave radiation in the form of infrared waves. These can be seen with an infrared camera.
Can you classify ordinary light as ionizing radiation?
Yes, as long as there is an element or perhaps even a compound that would undergo some form of oxidation due to the absorbing of the particular wave-length then that wave-length could be termed ionizing radiation. I know for a fact that selenium oxidizes under yellow light.
Will electromagnetic radiation with a longer wave length travel through space slower than one with a shorter wave length?
The speed of electromagnetic radiation stays constant at a speed of 299,792,458 metres per second.
What has the longest wave length infrared radiation radio wave ultra violet radiation visible light micro waves gamma radiation or x rays?
Radio waves have the longest wavelengths.
What form of radiation is the shortest wave length?
The form that we call "gamma rays".
How can cellphones make radiation?
Cellphones use microwave radiation to send and receive. Radios do the same, but with long wave or short wave.
Does the radiation emitted by earth's surface have longer or shorter wavelengths compared to solar radiation?
The radiation emitted by Earth's surface has longer wavelengths compared to solar radiation. Earth emits long-wave radiation in the infrared range, while solar radiation consists of shorter-wave radiation in the visible and ultraviolet ranges.
