According to Wein's Law, the peak wavelength at which a blackbody radiates most depends on its

• radius

• temperature

• direction of motion

• mass

• magnetic fields

What side of a blackbody radiation curve has a steep drop off on its distribution curve?

• The long wavelengths

• The short wavelengths

• both side drop off equally

• It's random

As a star's temperature increases, the frequency of peak emission also increases.

• True

• False
