Which statement about electromagnetic wavelength is TRUE?

Question

Quizplus · Accepted Answer

The energy of electromagnetic radiation is inversely proportional to its wavelength. As wavelength increases, energy decreases. This is known as the wave-particle duality principle, which states that electromagnetic radiation behaves both like waves and like particles, known as photons.

Note: B is not entirely accurate as there are electromagnetic wavelengths longer than one meter, such as radio waves. C is not accurate as only a small portion of electromagnetic wavelengths are visible to the human eye, specifically those with wavelengths between 400 and 700 nanometers. D is not accurate as gamma radiation is not a "moving" wavelength, but rather a type of electromagnetic radiation with very high frequency and energy.
