Answer:
Frequency = 667 MHz.
EM
Explanation:
The radio waves are the electromagnetic waves of a particular range of frequencies.
Unlike the sound waves which require a medium to propagate, the radio waves can travel in a vacuum.
The frequency of the radio waves ranges between 300 MHz to 600 MHz.
The relation between the frequency and wavelength is given by the relation
f = c / λ Hz
Where c is the velocity of electromagnetic waves. c = 3 x 10⁸ m/s
Given that the wavelength, λ = 0.045 m
Substituting in the above equation
f = 3 x 10⁸ m/s / 0.045 m
= 667 MHz
Hence, the frequency of the radio waves is, f = 667 MHz
It is electromagnetic radiation (EM).
