Final answer:
Electrons, photons, protons, and neutrons all exhibit wave-particle duality. Electromagnetic waves are transverse waves, with properties of frequency, amplitude, and period tied to both particle and wave models of light.
Step-by-step explanation:
The entities that exhibit properties of both waves and particles include electrons, photons, protons, and neutrons. These subatomic particles demonstrate wave-particle duality, a fundamental concept in quantum mechanics.
Photons are known as the quanta of light and are integral in phenomena such as the photoelectric effect and Compton scattering, involving interactions between a photon and an electron. Electrons are utilized in devices such as electron microscopes, exploiting their wave-like behavior to achieve high resolution imaging. Protons and neutrons, while commonly regarded as particles due to their mass, also exhibit wave-like characteristics, as evidenced by their involvement in scattering experiments and the concept of de Broglie matter waves applicable to all particles in motion.
Electromagnetic waves, such as light, are transverse waves, and terms like frequency, amplitude, and period are attributable to both the particle and wave models of light, highlighting how these properties are integral to understanding wave-particle duality.
