Question

Radio waves have a longer wavelength than microwaves. What else is true
about radio waves?

Answer 1

As it was explained in the Introductory Article on the Electromagnetic Spectrum, electromagnetic radiation can be described as a stream of photons, each traveling in a wave-like pattern, carrying energy and moving at the speed of light. In that section, it was pointed out that the only difference between radio waves, visible light and gamma rays is the energy of the photons. Radio waves have photons with the lowest energies. Microwaves have a little more energy than radio waves. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays.

That should be able to help answer your question :)

Answer 2

The accurate statement is C: Radio waves have a higher frequency than microwaves due to their longer wavelength.

The correct statement about radio waves in comparison to microwaves is C. They have a higher frequency than microwaves. Wavelength and frequency are inversely proportional, meaning as the wavelength increases, the frequency decreases. Since radio waves have a longer wavelength than microwaves, they correspondingly have a lower frequency.

The energy of a wave is directly related to its frequency, so option B, stating that radio waves have more energy than microwaves, is incorrect. Additionally, option D is false because amplitude refers to the height of a wave, and it is not necessarily correlated with wavelength or frequency.

In summary, the accurate statement is C: Radio waves have a higher frequency than microwaves due to their longer wavelength.
