Solution: λ = c / f = (3 x 10^8 m/s) / (2.45 x 10^9 Hz) = 0.122 m
S = (1 W * 10) / (4 * π * (100 m)^2) = 0.079 W/m^2

The wavelength of a radio wave can be calculated using the formula:
Solution: S = (P_t * G) / (4 * π * r^2) = (1 W * 10) / (4 * π * (100 m)^2) = 0.079 W/m^2
Problem 2: A microwave oven uses a frequency of 2.45 GHz to heat food. What is the wavelength of this radiation?
