How many photons are present in 1cm3 of radiation at 727°C? What is their average energy?
We need to determine the number of photons per cm³ and their average energy in blackbody radiation at 727°C (or 1000 K). ### Step 1: Given Data - Temperature: \( T = 1000 \) K - Volume: \( V = 1 \text{ cm}^3 = 10^{-6} \text{ m}^3 \) - Constant for integral: \[ \int_0^\infty \frac{x^2 dx}{e^x - ______ ____ _____ _______ ___ _______ _____.
