Which statement correctly lists the order of the electromagnetic spectrum from longest wavelength to shortest?

Explanation:
Longer wavelengths correspond to lower frequency and lower energy, while shorter wavelengths have higher frequency and higher energy. In vacuum, all electromagnetic waves travel at the same speed, so wavelength and frequency are inversely related (λf = c). When we list them from longest to shortest wavelength, the order is Radio, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma. This sequence reflects the gradual increase in energy per photon as wavelength gets shorter. Lists that start with Gamma or mix up the segments (like putting Radio after higher-energy waves) don’t follow this inverse relationship between wavelength and energy.
