What is Vega spectral class?
The spectral class is A0Va.
How does the luminosity of a blackbody vary with its surface temperature?
Both the absorption and the luminosity of a blackbody in equilibrium increase in magnitude with increasing temperature, and the spectral distribution of the luminosity increases in frequency (decreases in wavelength).
What is the spectral class of Antares?
Antares has a spectral class of M1LB.
When was Spectral Mornings created?
Spectral Mornings was created in 1979-01.
Is spectral type k hotter then spectral type a?
No. K spectral type stars (which are orange) temperature is ranging from 5,000-3,500. A spectral type stars (which are blue-white) temperature is ranging from 7,500-11,000.
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.
Do action-at-a-distance forces require physical contact between objects?
No. A couple of examples:- . The Cosmic Microwave background, is the residual radiation signature left over from the time of the creation of the Universe from the Big Bang. . The determination, by means of a spectroscope, of the spectral lines indicating the presence of particular elements in a distant star. . You may argue that the traffic microwave radar has its waves impinging on the target vehicle, but most would consider this a non-contact measurement.
