S = (1 W * 10) / (4 * π * (100 m)^2) = 0.079 W/m^2
Here is a sample PDF version of the solution manual:
Using the same formula as before:
Solution: λ = c / f = (3 x 10^8 m/s) / (100 x 10^6 Hz) = 3 m
Problem 2: A microwave oven uses a frequency of 2.45 GHz to heat food. What is the wavelength of this radiation?
λ = (3 x 10^8 m/s) / (100 x 10^6 Hz) = 3 m
Solution: λ = c / f = (3 x 10^8 m/s) / (2.45 x 10^9 Hz) = 0.122 m
