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.

A newly formed protostar will radiate primarily at which wavelength?
infrared
The material that accretes onto a neutron star or black hole is expected to emit x-rays because?
Accretion disks generally are energetic because of gravitational compression of infalling matter, and frictional forces which heat the matter in the accretion disk. The frequency depends on the mass of the central body. Protostellar accretion disks emit in the infrared, the higher speed and friction associated with the more intense gravity of neutron stars and black holes cause them to radiate in the higher x-ray frequencies of the electromagnetic spectrum.
If you double the Kelvin temperature of a hot piece of steel how much more energy will it radiate per second?
twice as much
In the process of electricity what flows through the wires?
Its temperature increases. It continues to radiate a spectrum of light ("black body") representative of its new higher temperature. At some level of current, we see it as a source of visible light.
Why electrons does not radiate energy?
It cannot radiate because it cannot remain single but joins with a positive ion or proton.
If a star has a surface temperature of 36000 K at what wavelength will it radiate the most energy?
80.556nm λmax = 2.9 x 10^6 / T Where λmax is the max wavelength and T is in kelvin
A newly formed protostar will radiate primarily at which wavelength?
infrared
A newly former protostar will radiate primarily at which wavelength?
Infrared
What is the medium for light?
Light, whatever the wavelength, does not need a medium in order to radiate.
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 objects can radiate energy?
All objects radiate energy at a rate depending on their temperature.
What is the medium for ultraviolet lights?
Light, whatever the wavelength, does not need a medium in order to radiate.
When do objects radiate heat?
When their temperature is greater than the temperature of the adjacent zones.
Why is your body temperature not the same as room temperature?
because you would not be able to radiate heat out of your body
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.
