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

The correct answer is:

Radio waves have longer wavelengths and lower frequencies than microwaves

Explanation:

Microwaves have wavelength between 1 mm and 1 meter, while radio waves have wavelength greater than 1 meter, so radio waves have longer wavelengths.

Frequency is inversely proportional to the wavelength, according to the relationship:

where c is the speed of light and is the wavelength. From this equation, we immediately understand that the longer the wavelength, the lower the frequency, and viceversa. Therefore, since radio waves have longer wavelengths, they have lower frequencies than microwaves.
