Refraction of light and wavelength

AI Thread Summary
The discussion focuses on calculating the angle of refraction and the wavelength of light when it transitions from air to water. The angle of refraction can be determined using Snell's Law, which relates the angles and indices of refraction of the two media. A key point raised is that the frequency of light remains constant during this transition, which is crucial for calculating the new wavelength in water. The relationship between wavelength and frequency is emphasized as essential for solving the problem. Ultimately, understanding these principles is necessary to find the wavelength of light in water.

Light of wavelength 680 nm in air enters water making an angle of 40 degrees with the normal. Find the angle of refraction and the wavelength of light in water.

I found the angle of refraction, but I don't know how to calculate the wavelength with this information.

hi siobhanbree! welcome to pf! :smile:

hint: does the frequency change? what is the relation between wavelength and frequency? :wink:

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...
