What else can I help you with?
Most of the radiation incident upon the Earth falls within the?
Most of the radiation incident upon the Earth falls within the visible and near-infrared portions of the electromagnetic spectrum.
Where does the earth emits radiation with greatest intensity at?
The Earth emits radiation with the greatest intensity in the infrared part of the spectrum, due to the thermal energy emitted by the surface. This is known as terrestrial radiation and plays a significant role in the Earth's energy balance.
How does the radiation emitted from the sun differ from the radiation emitted by earth?
The Sun emits a broader spectrum of radiation, including visible light, ultraviolet rays, and infrared radiation, while Earth primarily emits infrared radiation due to its lower temperature. The Sun's radiation is much more intense and has higher energy compared to the radiation emitted by Earth.
What wavelength of radiation is reradiated by the Earth upward?
The Earth reradiates longwave infrared radiation, with a peak wavelength around 10 micrometers. This is due to the Earth's relatively cool temperature compared to the Sun, causing it to emit radiation in the infrared part of the electromagnetic spectrum.
Where does radiant energy transmitted to earth come from?
Radiant energy transmitted to Earth primarily comes from the Sun. The Sun emits electromagnetic radiation across a broad spectrum, including visible light, ultraviolet light, and infrared radiation. This radiant energy is responsible for heating the Earth and driving various natural processes.
Most of the radiation incident upon the Earth falls within the?
Most of the radiation incident upon the Earth falls within the visible and near-infrared portions of the electromagnetic spectrum.
The Earth's atmosphere filters out certain wavelengths of the electromagnetic spectrum?
Yes, Earth's atmosphere filters out certain wavelengths of the electromagnetic spectrum, such as most ultraviolet radiation and some infrared radiation, before they reach the surface. This filtering is important for protecting life on Earth from harmful radiation.
What does the sun have to do with the electectmagntic spectrum?
The sun emits a wide range of electromagnetic radiation across the spectrum, from radio waves to gamma rays. Different layers and processes on the sun produce various types of radiation, which contribute to the overall electromagnetic spectrum that reaches Earth. Measurements of solar radiation across the spectrum help scientists understand the sun's behavior and its effects on various processes on Earth.
What type of radiation is responsible for heating effect in sunlight?
The Sun emits infrared radiation, as well as a broad spectrum of other rays of electromagnetic radiation. It is the infrared band, that just beyond (and just longer in wavelength) what we see as the color red, which reacts with matter to increase its temperature. Infrared from sunlight heats the Earth's surface and atmosphere.
what is the total range of energy which reaches the earth from the sun is called what?
The total range of energy that reaches the Earth from the Sun is called the solar spectrum. This spectrum includes various forms of electromagnetic radiation, such as visible light, ultraviolet, and infrared radiation. The solar spectrum is crucial for supporting life on Earth, driving weather patterns, and influencing climate.
Where does the earth emits radiation with greatest intensity at?
The Earth emits radiation with the greatest intensity in the infrared part of the spectrum, due to the thermal energy emitted by the surface. This is known as terrestrial radiation and plays a significant role in the Earth's energy balance.
What is radiation from the sun called that provides heat?
The radiation from the sun that provides heat is called infrared radiation. This type of radiation is responsible for warming the Earth's surface and is part of the electromagnetic spectrum.
How does the radiation emitted from the sun differ from the radiation emitted by earth?
The Sun emits a broader spectrum of radiation, including visible light, ultraviolet rays, and infrared radiation, while Earth primarily emits infrared radiation due to its lower temperature. The Sun's radiation is much more intense and has higher energy compared to the radiation emitted by Earth.
What is the name for the change in the star's spectrum when it moves away from earth?
That is called "redshift". The frequency of the radiation decreases.
Does solar radiation contain a complete spectrum of all forms of electromagnetic radiation?
Yes, solar radiation contains a broad spectrum of electromagnetic radiation, from radio waves to gamma rays. This spectrum includes infrared, visible light, and ultraviolet rays, contributing to the energy output and various effects on Earth.
How long are the wavelengths of radiation emitted by Earth are?
The wavelengths of radiation emitted by Earth are primarily in the infrared spectrum, ranging from about 5 to 100 micrometers. This is known as terrestrial or thermal radiation, and it is a form of heat energy emitted by the Earth's surface and atmosphere.
The sun emits its greatest intensity of radiation in?
The sun emits its greatest intensity of radiation in the visible light spectrum. This is the range of wavelengths that our eyes can detect, making it the most intense and dominant type of radiation that reaches the Earth.
