What else can I help you with?
Are the radiation wavelengths emitted by the sun longer than those emitted by the earth?
The radiation emitted by the Earth peaks around 10 microns, whereas that from the sun peaks under 1 micron. This is why Earth's radiation is referred to as longwave and solar radiation as shortwave, commonly. All objects emit radiation because all objects have a temperature. In fact, using Wien's Law you can very simply calculate the wavelength, lambda, of maximum emission: lamda(max) = c/T where c is a constant (2897) and T is the temperature of the emitting surface in Kelvin.
Is the earths radiation shortwave or longwave?
Earth's radiation is primarily longwave. Shortwave radiation from the sun enters the Earth's atmosphere, where some is absorbed and re-radiated as longwave radiation. This longwave radiation is what is emitted back out into space.
What does energy generated on earth return to space as?
Energy generated on Earth is eventually returned to space in the form of infrared radiation emitted by the Earth's surface. This radiation is a result of the Earth absorbing and then reradiating solar energy received from the Sun.
What are the similarities between insolation and Terrestrial radiation?
Both insolation and terrestrial radiation involve the transfer of energy from the sun to the Earth. They are both forms of electromagnetic radiation, with insolation being solar radiation that reaches the Earth's surface and terrestrial radiation being the heat energy emitted by the Earth back into the atmosphere.
How does solar radiation reach the surface of the earth?
Solar radiation reaches the surface of the Earth through the process of electromagnetic radiation emitted by the Sun. This radiation travels through space and reaches Earth's atmosphere, where it penetrates and warms the surface of the planet. The atmosphere helps block harmful radiation while allowing sunlight to reach the surface.
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.
What best describes the primary wavelength of radiation emitted by Earth's surface?
they are longer than those emitted by the sun.
The wavelengths of radiation emitted by Earth are?
Earth emits radiation across a wide range of wavelengths, including infrared, visible light, and some ultraviolet. This radiation is primarily determined by the temperature of Earth's surface and atmosphere.
Is speed of radiation emitted by the earth faster than the sun's?
both are the same = c
Is ultraviolet radiation the energy emitted by earth?
No, ultraviolet radiation is not emitted by the Earth itself. Ultraviolet radiation comes from the sun and is a form of electromagnetic radiation with shorter wavelengths than visible light. Earth's atmosphere filters and absorbs some of the incoming ultraviolet radiation before it reaches the surface.
Are the radiation wavelengths emitted by the sun longer than those emitted by the earth?

Definition of solar radiation?
Solar radiation refers to the energy emitted by the sun in the form of electromagnetic waves. This radiation provides the Earth with light and heat, playing a crucial role in various natural processes like photosynthesis and weather patterns. It is the primary source of energy for the planet.
What is a form of oxygen that protects us from high-energy radiation emitted by the sun?
Ozone is a form of oxygen that protects us from high-energy radiation emitted by the sun. It is found in the Earth's stratosphere and absorbs the majority of ultraviolet (UV) radiation before it reaches the Earth's surface, helping to shield living organisms from its harmful effects.
What are four types of radiation from the sun?
The four types of radiation from the sun are visible light, ultraviolet (UV) radiation, infrared radiation, and radio waves. These types of radiation are emitted by the sun and travel through space to reach Earth. Each type of radiation has different properties and impacts on the Earth's environment.
What region in the stratosphere protects the earth from harmful ultraviolet radiation emitted by the sun?
The ozone layer in the stratosphere is the region that protects the Earth from harmful ultraviolet radiation emitted by the sun. Ozone molecules absorb and block a significant portion of the Sun's harmful UV rays from reaching the Earth's surface, helping to safeguard life on our planet.
Why is heat from the sun transferred through radiation?
Heat from the sun is transferred through radiation because electromagnetic waves, such as light and infrared radiation, are emitted by the sun and travel through the vacuum of space to Earth without the need for a medium. This radiation is absorbed by the Earth's atmosphere and surface, causing an increase in temperature.
