question 11 (1 point)
which of the following statements regarding the quantum theory of light is correct?
light can only travel as a wave
light is composed of discrete particles with mass
light travels as waves with mass
light is composed of discrete mass - less particles
light is neither particle - like or wave - like

Explanation:

According to the quantum theory of light, light is composed of discrete mass - less particles called photons. Light has a dual nature (wave - particle duality). It is not just a wave (so the first option is wrong). Photons (the particles of light) have no mass (so the second and third options are wrong). And light does have wave - like and particle - like properties (so the fifth option is wrong).

Answer:

Light is composed of discrete mass - less particles.
