A microwave oven uses a frequency of 2.45 GHz to heat food. What is the wavelength of this radiation?
S = (P_t * G) / (4 * π * r^2)
Here is a sample solution manual for electromagnetic waves and radiating systems:
where λ is the wavelength, c is the speed of light (approximately 3 x 10^8 m/s), and f is the frequency.
Using the same formula as before:
