Is the color of star an effect of its temperature?
Yes. The apparent colour of a star is related to the peak wavelength of the light it emits. According to Wien's displacement law (look it up in Wikipedia) the peak wavelength is inversely proportional to the temperature. The higher the temperature, the shorter the peak wavelength. Wavelength decreases as one moves from red to blue in the visible spectrum, so a red star is cooler than a blue one.
What form of electmagnetic waves does the sun give off?
The Sun emits radiation in all parts of the Electromagnetic Spectrum. However, the strongest intensity radiation is at wavelength of around 450 nanometers. This is in the visible region.
What spectrum does the sun emit?
The Sun emits radiation across almost the entire electromagnetic spectrum.
The sun emits its greatest intensity of radiation in?
The sun emits its greatest intensity of radiation in a spectral region. The spectral region the sun's radiation emits to is the visible region of the spectrum.
How did the sun get its color?
The sun's color results from the temperature of its outer layer, which emits light in the yellow part of the visible spectrum. Hotter stars tend to emit more light in the blue part of the spectrum while cooler stars are more reddish.
Dispersing light from a hot wire which emits white light gives what type of spectrum is it?
A hot, glowing wire emits all wavelengths (or colors) of light. This is sometimes called "blackbody radiation." Since all colors are present, you will get a continuous spectrum.

What determines the kind of wavelength and the amount of radiation that an object emits?
just had this on a test, the answer is Temperature
What is the relationship between wavelengths and temperature?
There is a relationship between the temperature of an object and the wavelength at which the object produces the most light. When an object is hot, it emits more light at short wavelengths while an object emits more light at long wavelengths when it is cold. The amount of radiation emitted by an object at each wavelength depends on its temperature.
How do colors tell you about the temperature of a star?
The colder a star is the longer the light waves it emits. Light wavelength is what we perceive as color.
Is the Hg emission spectrum continuous or discrete?
Hg emission is discrete, that's why you can only see certain (discrete) frequencies, as excited electrons fall from one level to another. A heated light bulb, on the other hand, emits a continuous spectrum from all of its variously vibrating charges.
Why is Earth's atmosphere mainly heated from the ground up?
Solar radiation mostly passes through the atmosphere without heating it, due to its wavelength. It does not pass through the ground, however, and it heats the ground. The ground emits radiation at a wavelength dependent on its temperature. This radiation happens to be in the thermal infrared part of the spectrum, or in other words, sensible heat. Therefore, the atmosphere is heated by the surface, whereupon the heat tends to rise and heat the lower atmosphere.
How does the frequency of radiant energy relate to the absolute temperature of the radiating source?
A low temp source emits low-frequency, long wavelength waves. A medium temp source emits medium frequency, medium wavelength waves. A high temp source emits high frequency, short wavelength waves.
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
Why does a red star shine red?
Stars emit light because they are hot. When a hot object glows the color of light it emits depends on the temperature. The higher the temperature, the shorter the wavelength of light. The shortest wavelength of visible light is red Therefore the stars with the lowest temperature glow red.
What is the relationship between the temperature of a radiating body and the wavelength it emits?
The temperature of the radiating body determines the intensity and characteristics of the radiation it emits. Two electromagnetic radiation principles describe the relationship between a radiating body�s temperature and the radiation it emits. 1. Stefan-Boltzmann�s Law: Hotter objects emit more total energy per unit area than colder objects. 2. Wein�s Displacement Law: The hotter the radiating body, the shorter the wavelength of maximum radiation.
What form of electmagnetic waves does the sun give off?
The Sun emits radiation in all parts of the Electromagnetic Spectrum. However, the strongest intensity radiation is at wavelength of around 450 nanometers. This is in the visible region.
