A. The Sun's energy leaves as radiation of a single wavelength but can change wavelengths along the way, with the shortest wavelengths being particles that gained the most energy on the path to Earth.

B. The Sun's energy leaves as radiation of a single wavelength but can change wavelengths along the way, with the shortest wavelengths being particles that lost the most energy on the path to Earth.
C. The Sun's energy arrives as radiation with a wide range of wavelengths and the more energetic the wave the shorter the wavelength.
D. The Sun's energy arrives as radiation with a wide range of wavelengths and the more energetic the wave the longer the wavelength.
which is true

C. The Sun's energy arrives as radiation with a wide range of wavelengths and the more energetic the wave the shorter the wavelength.

how do radio waves compare to gamma waves in terms of energy, frequency, and wavelength?

Radio waves have lower energy, lower frequency, and longer wavelength compared to gamma waves. Gamma waves have higher energy, higher frequency, and shorter wavelength.
