# Blackbody Radiation Question

**1. The problem statement, all variables and given/known data**

The temperature of a blackbody is 500 C. If the intensity of the emitted radiation, 2.0 W/m^2, were due entirely to the most intense frequency component, how many quanta of radiation would be emiteed per second per square meter?

**2. Relevant equations**

λmaxT = 2.90 x 10^-3 m K

**3. The attempt at a solution**

I’m not sure where to begin or how to use intensity.

500 C = 773.15 K

I calculated λmax = 2.90 x 10^-3 m K / 773.15 K = 3750 nm or 3.75 x 10 ^-6 m. I’m not sure where to go from here. Please help. Thank you!
