question 1 (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), so it is not just a wave (eliminating the first option). Photons have no mass (eliminating the second and third options). And light does have both wave - like and particle - like properties (eliminating the fifth option).

Answer:

Light is composed of discrete mass - less particles
