Why are the supergiant stars so bright even though they are not very hot?
A relatively low surface temperature means that reg giants radiate relatively little energy per area unit, but since they have a very large surface area, the total amount of energy radiated is enormous.
If a red star and a white star radiate energy at the same rate can they be the same size If not which must be the largest Why?
They cannot be the same size. The red star must be larger. Red stars are cooler that blue stars and so radiate less energy for a given amount of surface area. In order to radiate the same amount of energy as a blue star, the red star must therefore have a larger surface area.
What is a wide range of energy waves that radiate from the sun?
This refers to electromagnetic waves.These are:Radio waves (biggest wavelength)MicrowavesInfrared wavesVisible waves (light, the rainbow spectrum)Ultraviolet wavesX-ray wavesGamma waves (smallest wavelength).
Does the sun radiate both visible energy and invisible energy?
yes.
Does the sun radiate visible and invisible energy?
Yes.
What objects can radiate energy?
All objects radiate energy at a rate depending on their temperature.
If the inner accretion disk around a black hole has a temperature of 1000000 K at what wavelength will it radiate the most energy?
For a thermal radiation source, the peak of the blackbody radiation curve is at a photon energy 2.8 times the temperature in electron-volts. The temperature in electron-volts is 1/11,600 times the temperature in Kelvin. Use E = hv to convert from the photon energy (E) to photon frequency, using Plank's constant h. Use v = c/(lambda) to convert from the photon frequency to the wavelength. The result: these hot plasmas radiate X-rays, and the peak wavelength is about 50 Angstroms, i.e. 5 nm.
Human body temperature is about 310 K 98.6 degree F At wavelength do humans radiate the most energy What kind of radiation do you emit?
The Wien’s law for maximum intensity is, Here, is the wavelength of maximum intensity and T is the temperature of human body. Rearrange the above expression for . Substitute for T to find . So the maximum energy is radiated at 9355.83nmK. Humans emit infrared off radiation which is electromagnetic radiation with a frequency lower than visible light.
What form of energy in energy of house lights?
House lights radiate energy as electromagnetic waves in the wavelength bands of heat and visible light.
Does a drum set radiate sound energy?
Yes, a drum set can radiate sound energy when the surface of the drum vibrates on striking it to set particle molecules in air to transfer energy in a wave form and radiate out.
What is the giant star?
The largest stars - that is, largest in diameter - are usually red. This is related to the fact that their surface temperature is relatively low. They still radiate huge amounts of energy though, due to their large surface.

What is the connection between a star's surface temperature and its color?
Stars that are cool normally radiate ther energy in the electromagnetic spectrum as red. Even though all the sky appear to be white, Hot stars radiate much longer wave lengths, causing an almost blue color to be emitted.
If Earths surface is heated does it radiate most of the energy back into the atmosphere as ultraviolet radiation?
No. It radiates most energy back as infarred radiation.
