Problem 1: What is the wavelength of a radio wave with a frequency of 100 MHz?

Solution: λ = c / f = (3 x 10^8 m/s) / (100 x 10^6 Hz) = 3 m

An antenna has a gain of 10 dB and is used to transmit a signal at a frequency of 1 GHz. What is the power density of the signal at a distance of 100 m from the antenna?

Solution: S = (P_t * G) / (4 * π * r^2) = (1 W * 10) / (4 * π * (100 m)^2) = 0.079 W/m^2

Using the same formula as before:
