Question 43

Which of the following statements best describes how the propagation of light, reflection, and refraction are explained by the wave model and the particle model of light?

Accepted Answer

The wave model explains reflection and refraction as the bending of light waves when they encounter a boundary between two different mediums, while the particle model

Answer

The wave model explains the propagation of light as the oscillation of electromagnetic waves, while the particle model describes light as a stream of tiny particles called photons.

Answer

Both the wave model and the particle model explain the propagation of light as the movement of energy packets called quanta, but the wave model focuses on the behavior of light waves, while the particle model focuses on the discrete nature of light.

Answer

The wave model explains reflection as the bouncing back of light waves from a surface, while the particle model explains it as the emission of photons by a reflecting object. The wave model also explains refraction as the bending of light waves when they pass through a different medium, while the particle model explains it as the change in direction of photons due to interactions with atoms or molecules.

Question 44
