Blackbody radiation

Concept Test:

If a 3000 K blackbody emits with a peak wavelength of 1000 nm, what is the peak wavelength of the radiation emitted by your body (300 K)?

A) 100 nm B) 10,000 nm

C) 100,000 nm D) 2,000 nm

How much more energy (per square meter) does it the 3000 K blackbody emit?

A) 10 times as much B) 1000 times as much

C) 1/10th as much D) 10,000 times as much

Just about every object you can imagine emits blackbody radiation. Even you!
