Question

How do the wavelengths and frequencies of microwaves compare to wavelengths and frequencies of radio waves? Microwaves have


Shorter wavelengths and lower frequencies


Longer wavelengths and lower frequencies


Shorter wavelengths and higher frequencies

Answer 1

Shorter wavelengths and higher frequencies.

Explanation: for electromagnetic waves c = λ·f, so a shorter wavelength means a higher frequency. Microwaves occupy the portion of the radio spectrum with shorter wavelengths (≈1 m to 1 mm) and therefore higher frequencies than longer-wavelength radio waves.
