Snell's Law and the particle model for light

AI Thread Summary
Snell's Law describes the relationship between the angles of incidence and refraction when light passes through different media, indicating how light bends at boundaries. The calculated value of 1.22 represents the refractive index, which is the ratio of the speed of light in a vacuum to its speed in the medium. This value does not provide definitive evidence for or against the particle model of light, as both wave and particle theories can explain refraction. The discussion also highlights that evidence for the particle model is more convincingly found in phenomena like the photoelectric effect. Understanding these concepts is crucial for grasping the nature of light in physics.

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.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
