Question

1. which statement correctly describes photons?

photons behave like particles but not waves.
photons behave like waves but not particles.
photons are particles of light and have a wavelength.
photons are particles of light without a wavelength.

Explanation:

Photons are particles of light and have a wavelength. This is because of the wave - particle duality of light. Light (and thus photons) can exhibit both wave - like properties (such as having a wavelength) and particle - like properties. The first two options are incorrect as photons do not behave like only particles or only waves. The last option is incorrect as photons do have a wavelength.

Answer:

Photons are particles of light and have a wavelength.
