Sunlight reaching Earth is most affected by the law of?
Blackbody radiatiob
How does the color indicate the temperature of a star?
because since its very hot the hotter it gets it starts to melt the color on the star. For Example blue stars. there the hottest star.
What is the relationship between star color and star temperature?
Stars appear to be exclusively white at first glance. But if we look carefully, we can notice a range of colors: blue, white, red, and even gold. In the winter constellation of Orion, a beautiful contrast is seen between the red Betelgeuse at Orion's "armpit" and the blue Bellatrix at the shoulder. What causes stars to exhibit different colors remained a mystery until two centuries ago, when Physicists gained enough understanding of the nature of light and the properties of matter at immensely high temperatures. Specifically, it was the physics of blackbody radiation that enabled us to understand the variation of stellar colors. Shortly after blackbody radiation was understood, it was noticed that the spectra of stars look extremely similar to blackbody radiation curves of various temperatures, ranging from a few thousand Kelvin to ~50,000 Kelvin. The obvious conclusion is that stars are similar to blackbodies, and that the color variation of stars is a direct consequence of their surface temperatures. Cool stars (i.e., Spectral Type K and M) radiate most of their energy in the red and infrared region of the electromagnetic spectrum and thus appear red, while hot stars (i.e., Spectral Type O and B) emit mostly at blue and ultra-violet wavelengths, making them appear blue or white. To estimate the surface temperature of a star, we can use the known relationship between the temperature of a blackbody, and the wavelength of light where its spectrum peaks. That is, as you increase the temperature of a blackbody, the peak of its spectrum moves to shorter (bluer) wavelengths of light. This is illustrated in Figure 1 where the intensity of three hypothetical stars is plotted against wavelength. The "rainbow" indicates the range of wavelengths that are visible to the human eye.
What is a blackbody radiator?
Blackbody raditaition is a form of electromagnetic energy that is created from a blackbody (something that reflects or absorbs all incident energy). If a blackbody is in thermodynamic equilibrium (constant non-changing temp. 0 net force) it will radiate blackbody radiation which changes with temperature. Higher temp. calls for shorter wavelengths and higher intensity. The hue is generally infared and cant be seen. some times you can see a faint red or orange glow. glad to answer.
Who invented the Infrared Thermometer?
The infrared thermometer is a laser thermometer that uses blackbody radiation to measure temperature. An infrared thermometer design was patented in the 1980s by several employees of Intelligent Medical Systems, Inc. A compact infrared thermometer was then patented in 2002 by ZyTemp.
Can perfectly blackbody is possible?
no,perfectly blackbody is not possible.Lamp black is 99% blackbody.because 100% absorption and 100%emission is practically not possible .
Which option is the best blackbody radiator?
The Sun
What has the author R J De Young written?
R. J. De Young has written: 'Scaling blackbody laser to high powers' -- subject(s): Lasers, Blackbody radiation 'Lasant materials for blackbody pumped-lasers' -- subject(s): Solar-pumped lasers, Lasers in astronautics, Energy conversion, Laser pumping, Blackbody radiation, Laser cavities, Laser propulsion, Black body radiation 'A blackbody-pumped CO-N' -- subject(s): Lasers
The blackbody curve depends on what single property?
temperature
What is the glow of a hot object?
It's Blackbody Radiation
Which is most perfect blackbody on Earth?
Serena Williams
What is a perfect absorber or emitter of radiation called?
Blackbody
What is the scientific term for florescent light bulbs?
blackbody radiation
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 a perfect black body?
A perfect blackbody absorbs all radiation incident on it and It emits electromagnetic radiation in the form of thermal radiation from its surface. OR A perfect blackbody is a perfect emitter and perfect absorber.
Sunlight reaching Earth is most affected by the law of?
Blackbody radiatiob
What were the units of light emmited by blackbody radiation originally called?
Quanta
