Question

The radio waves have a frequency of 4.8×1094.8×109 Hz. The wave speed of electromagnetic waves is 3.0×1083.0×108 m/s. Calculate the wavelength of the radio waves. Give your answer to 2 significant figures.

(a) 0.06 m
(b) 0.125 m
(c) 0.0625 m
(d) 0.1250 m

Answer 1

The wavelength of the radio waves is 0.0625 m.

Step-by-step explanation:

To calculate the wavelength of the radio waves, we can use the formula: wavelength = speed of wave / frequency. Given that the wave speed is 3.0×10^8 m/s and the frequency is 4.8×10^9 Hz, we can plug these values into the formula to get:

wavelength = (3.0×10^8 m/s) / (4.8×10^9 Hz) = 0.0625 m

Therefore, the wavelength of the radio waves is 0.0625 m.
