Answer:
C. Radio waves have longer wavelengths and lower frequencies than microwaves.
Explanation:
Radio waves and microwaves are both electromagnetic waves. They do not require a medium for their propagation.
These waves are produced as result of the vibration between electric and magnetic fields perpendicular to one another.
- On the electromagnetic spectrum, the waves are listed from left to right
- Along the spectrum, wavelength increases as frequency decreases.
- Energy also decreases to the right on the spectrum.
- Since microwaves comes before radio waves, they have shorter wavelength and higher frequency than micro waves.
