Final answer:
The particle property of light relevant to the provided options is the photoelectric effect, where photons eject electrons from the surface of a metal. Diffraction, however, indicates wave behavior of light, and when light transitions between mediums, its frequency remains constant while other aspects such as speed and wavelength may change.
Step-by-step explanation:
The particle property of light related to the options presented is b. Photoelectric effect. The photoelectric effect demonstrates that light can behave like particles, specifically photons, which are quanta of light. When light of a certain minimum frequency (or shorter wavelength) strikes a metal surface, it can eject electrons from the material, indicating that the light carries energy in discrete packets.
Answering the reference questions:
Diffraction indicates wave behavior, not particle behavior.When a monochromatic beam of light passes from air into water, the frequency of the light remains unchanged, although its speed and wavelength may change.In the context of the photoelectric effect, the energy of light increases as its frequency increases, not its speed, intensity, or wavelength.A photon is a quantum of light and exhibits properties akin to particles when it participates in interactions like the photoelectric effect.A quantum of light is called a photon.
