Snell's Law and the particle model for light

Click For Summary
SUMMARY

Snell's Law describes the refraction of light as it passes through different media with varying refractive indices. In the discussion, a value of 1.22 was calculated using the ratio of the sine of the angle of incidence to the sine of the angle of refraction, indicating a refractive index. This value supports the understanding of light's behavior but does not definitively favor the particle model over the wave model. The particle model is further evidenced by phenomena such as the photoelectric effect.

So I did a "waves in two depth medium refraction" lab and I measured the angle of incidence and the angle of refraction.

So doing the sin i/ sin R, I get the value of 1.22 for all the sets of data.

A question asks, do the values (1.22) serve as evidence for or against a particle model for light?

I'm new to this physics thing, and it definitely isn't my strong subject. So I'm wondering if someone can explain in their own words what Snell's law is about and what that value (1.22) means, in my context. Maybe then I can attempt to answer my question.

Snells law describes how a light ray refracts through a boundary between media with differing refractive indices. It cannot distinguish between wave and particle theories of light.

The value you get is = velocity of light in a vacuum / velocity of light in medium, called refractive index.

Anyway, I think the evidence for particle model of light is in the photoelectric effect.
