How determine surface temperature of a star?
The surface temperature of a star can be determined by analyzing its spectrum. Specifically, scientists can observe the peak wavelength of light emitted by the star and use Wien's Law, which relates the peak wavelength to the temperature of the emitting object. By measuring the peak wavelength, astronomers can calculate the surface temperature of the star.
How many light years away is betelgeuse?
Betelgeuse is approximately 600 light years from Earth.
How far is Betelgeuse from the sun?
Betelgeuse is about 640 light-years from the sun.
What does the red color of Betelgeuse mean?
The red color of Betelgeuse is due to its relatively low surface temperature compared to other stars, causing it to emit more red and orange light. This cooler temperature indicates that Betelgeuse is nearing the end of its life cycle and will eventually explode as a supernova.
How far away is Betelgeuse?
Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.
What is the emission wavelength equation used to calculate the specific wavelength of light emitted by a substance?
The emission wavelength equation used to calculate the specific wavelength of light emitted by a substance is c / , where represents the wavelength, c is the speed of light in a vacuum, and is the frequency of the light emitted.
What's the wavelength of the light emitted by the laser?
The wavelength of the light emitted by the laser is typically in the range of 400 to 700 nanometers.
What is the relationship between the wavelength of light and temperature in a given system?
The relationship between the wavelength of light and temperature in a given system is that as the temperature of the system increases, the wavelength of the light emitted by the system also increases. This is known as Wien's displacement law, which states that the peak wavelength of light emitted by an object is inversely proportional to its temperature.
A blackbody curve relates the wavelength of emitted light to?
the intensity of radiation emitted at that wavelength, giving a characteristic spectral distribution that depends only on the temperature of the object emitting the light.

Specifically, scientists can observe the peak wavelength of light emitted by the star and use Wien's Law, which relates the peak wavelength to the temperature of the emitting object. By measuring the peak wavelength, astronomers can calculate the surface temperature of the star.
Does uv light emitted by a star have a wavelength that is longer than the visible light emitted by the star?
Ultra violet radiation has a shorter wavelength than visible light; this is true regardless of whether it is a star or any other source that is emitting it.
What is the relationship between the color emitted by a fluorescent light and its corresponding wavelength in the electromagnetic spectrum?
The color emitted by a fluorescent light is directly related to its corresponding wavelength in the electromagnetic spectrum. Different colors of light have different wavelengths, with shorter wavelengths corresponding to colors like blue and violet, and longer wavelengths corresponding to colors like red and orange. The specific wavelength of light emitted by a fluorescent light determines its color appearance.
The wavelength of red light from 760nm in meters?
If a wavelength of light emitted from a particular red diode laser is 651 nm, its wavelength would be equivalent to 0.000000651 meters.
What quantum leaps would be associated with the greatest energy of emitted light?
Quantum leaps between energy levels that are farther apart would be associated with the greatest energy of emitted light. This is because energy and wavelength of emitted light are inversely proportional, so larger energy differences result in shorter wavelength (higher energy) light being emitted.
How many electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent?
The number of electrons emitted when calcium is flashed with light of a certain wavelength and intensity depends on the photoelectric effect, which is related to the energy of the photons hitting the metal. Without the energy of the photons and the work function of calcium, we cannot determine the number of electrons emitted.
A light is emitted from a laser.its frequency is 630THz.what is the wavelength and color?
You can get the wavelength by dividing the speed of light by the frequency. Don't forget that THz means 10 to the power 12 Hz.
What is the difference between emitted light and exciting light?
excited light is the light a chemical absorbs raising it from it's ground state to an excited state. Energy is released as heat and as light. Causes flourescence when chemical returns itself to its ground state. emitted light is the light emitted from the absorbing chemical. When this happens a substance(usually an organic) is emitting a light of longer wavelength after absorbing light of a shorter wavelength.
