Question

which statement correctly compares radio waves and microwaves?
radio waves have shorter wavelengths and higher frequencies than microwaves.
radio waves have longer wavelengths and higher frequencies than microwaves.
radio waves have shorter wavelengths and lower frequencies than microwaves.
radio waves have longer wavelengths and lower frequencies than microwaves.

Explanation:

Electromagnetic waves follow the relationship $c = \lambda f$, where $c$ is the speed of light (constant), $\lambda$ is wavelength, and $f$ is frequency. This means wavelength and frequency are inversely proportional. In the electromagnetic spectrum, radio waves occupy the range with the longest wavelengths, which corresponds to the lowest frequencies, while microwaves have shorter wavelengths and higher frequencies than radio waves.

Answer:

Radio waves have longer wavelengths and lower frequencies than microwaves.
