BLACK BODY RADIATION

What is a rule of infrared radiation

all bodies no matter what temperature, emit and absorb infrared radiation

What do hotter bodies do

radiate more infrared radiation in a given time

What is a perfect black body

an object that absorbs all of the radiation incident on it, does not reflect/transmit any radiation

Why are black bodies good emitters

they are good absorbers and would make the best possible emitters

What happens in a body at constant temperature

its absorbing radiation at the same rate as it is emitting radiation

When does the temperature of a body increase

when the body absorbs radiation faster than it emits radiation

What is the temperature of the Earth dependent on

the rates of absorption, emission of radiation, reflection of radiation into space
