Multiple Choice
A small particle of interplanetary material is heated by friction from a temperature of 400 K to 4000 K as it falls into the atmosphere of Earth and produces a meteor or a shooting star in the sky. If this object behaves like a perfect blackbody over this short time, how will its emitted radiation change as it is heated?
A) The intensity of the radiation will rise by a factor of 100, while the peak wavelength of emitted light will become shorter by a factor of 100, moving from the infrared to the ultraviolet.
B) The intensity of the radiation will rise by a factor of 10,000, while its peak wavelength will become longer by a factor of 10, moving from the visible to the infrared of heat radiation.
C) The emitted intensity of the radiation will rise by a factor of 10,000, while its peak wavelength will become shorter by a factor of 10, from infrared to red visible light.
D) The intensity of the radiation will rise by a factor of 10, while its peak wavelength will become shorter by a factor of 10, moving from the infrared to red visible light.
