The correct statement is:
A. Infrared waves have lower frequencies than ultraviolet waves. Since frequency and energy are directly proportional, infrared waves also have less energy than ultraviolet waves.
This statement is accurate because infrared waves indeed have lower frequencies than ultraviolet waves, and since energy is directly proportional to frequency (as described by the equation \( E = h f \), where \( E \) is energy, \( h \) is Planck's constant, and \( f \) is frequency), infrared waves will have less energy than ultraviolet waves.
