Here's why:
* Refraction is fundamentally a wave phenomenon: The bending of light as it passes from one medium to another (like from air to water) is best explained by the wave nature of light. This bending is a consequence of the change in speed of light as it enters a medium with a different refractive index.
* The particle model struggles with wave behavior: The particle model of light, based on photons, doesn't inherently explain wave-like behaviors like interference and diffraction, which are crucial for understanding refraction.
How the Wave Model Explains Refraction:
* Slower speed in denser medium: Light travels slower in denser materials (like water) than in less dense materials (like air). This change in speed is the key to refraction.
* Change in direction: When light enters a denser medium at an angle, one part of the wave front slows down before the other, causing the wave to bend.
In summary: While the particle model is important for understanding certain aspects of light, it is the wave model that provides the best explanation for refraction.
