Object that absorbs & emits all wavelengths of radiation
P=σAT4P = \sigma A T^4P=σAT4
5.67×10−85.67 \times 10^{-8}5.67×10−8 W m−2^{-2}−2 K−4^{-4}−4
Surface area AAA and fourth power of temp T4T^4T4
λmaxT=2.9×10−3\lambda_{\text{max}} T = 2.9 \times 10^{-3}λmaxT=2.9×10−3 m K
2.9×10−32.9 \times 10^{-3}2.9×10−3 m K
Peak wavelength decreases (shorter wavelengths)
Shifts to shorter wavelengths
I=P4πd2I = \frac{P}{4 \pi d^2}I=4πd2P
