Radio waves
Explicación
## Step 1The problem is asking us to identify which type of electromagnetic wave has the least energy. The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency or wavelength. The spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.## Step 2The energy of an electromagnetic wave is directly proportional to its frequency and inversely proportional to its wavelength. This means that the higher the frequency, the higher the energy, and the shorter the wavelength. Conversely, the lower the frequency, the lower the energy, and the longer the wavelength.## Step 3Given the options, radio waves have the lowest frequency and the longest wavelength, which means they have the least energy.
