Just take a minute to imagine the beautiful colors in the sunshine filtering through the trees. The peak in our sun's radiation spectrum comes at yellow-green wavelengths, like a delicate shade mixing together in a painting. It's a gentle reminder of the importance of warmth and light in our lives.
What else can I help you with?
The peak intensity of radiation from a star named Sigma is 2 x 106 nm. In what spectral band is thisThe peak intensity of radiation from a star named Sigma is 2 x 106 nm. In what spectral band is this?
The peak intensity of radiation from the star Sigma at 2 x 10^6 nm falls within the infrared spectral band. Specifically, this wavelength is far beyond the visible spectrum, which ranges from approximately 400 nm to 700 nm, and is classified as far-infrared radiation.
What percentage of the suns radiation is reflected by the clouds?
5%
Which planet has an atmosphere that protects life from the suns radiation?
The EARTH!!!!
What spectrum does the sun emit?
The Sun emits radiation across almost the entire electromagnetic spectrum.
Why is the suns spectrum and the moon's spectrum the same?
The sun and the moon's spectra are not the same. The Sun's spectrum shows continuous radiation across a range of wavelengths due to its high temperature, while the moon's spectrum shows reflected sunlight with absorption lines due to its lack of inherent light source. They have different compositions and physical properties affecting their spectra.
What is important about the peak wavelength of a thermal radiation spectrum?
The peak wavelength, is connected to the temperature of the objects. we have short peak wavelength when the temperature is high.
Do the hottest bodies produce the shorter wavelenghts of maximum radiation?
Hotter bodies emit wavelengths which peak at the shorter end of the spectrum.
What is the peak radiation for the hottest stars?
Eta Carinae is one of the hottest known stars, with a surface temperature of approximately 38000 Kelvins. According to Wien's displacement law, the peak radiation of Eta Carinae is 76 nanometers, which is far into the ultraviolet spectrum.
What is the peak wavelength of radiation?
This question has a real subtlety in it. The simplest answer is given by Wein's Law, sometimes called Wein's Displacement Law: The peak of the spectrum for any "blackbody" (this works approximately for stars and people, basically any opaque object). Wavelength of peak emission = (Stefan's constant, which you can look up) x 0.0029meter / temperature in Kelvins. According to this formula, the peak is in the green part of the spectrum. But a lot of light is given off across the visual part of the spectrum so it looks whitish to me. Here's the subtlety that few people realize. This all works only when you plot the spectrum as the emission per unit wavelength. You can also plot the emission per unit frequency. Then the peak is at a different location!
Is it radiation that when the sun makes you warm?
it is the suns radiation
What is radiation in water cycle?
the radiation is the suns heat
What portion of the spectrum does suns black body curve peak?
The Sun's black body curve peaks in the visible spectrum, specifically in the green portion around 500 nanometers. This is why our eyes have evolved to be most sensitive to this wavelength, making green a dominant color in our perception of sunlight.
How do the suns heat get to the earth?
Radiation
What is the wavelength of maximum intensity in sunlight?
The wavelength of maximum intensity in sunlight is around 500 nm, which is in the green portion of the visible spectrum. This wavelength corresponds to the peak of the solar radiation spectrum and is where the sun emits the most energy.
What part of the electromagnetic spectrum contains the majority of the suns rays?
IR, visible, UV. Our sun's radiation peaks in the yellow portion of the spectrum.
What does a blackbody spectrum look like?
A blackbody spectrum is smooth and continuous, showing a peak intensity at a specific wavelength that shifts to shorter wavelengths as temperature increases. It has a characteristic shape with most of the emitted radiation concentrated at shorter wavelengths.
What type of wavelength hot and cold objects have?
Hot objects emit shorter wavelengths, such as infrared radiation, while cold objects emit longer wavelengths like microwave radiation. This is known as blackbody radiation, where the temperature of an object determines the peak of its emitted spectrum.
