Light prapogate as wave or particle?

AI Thread Summary
Light behaves as both a wave and a particle, a concept known as wave-particle duality. The notion that light's behavior can be explained by increasing mass with speed is incorrect, as light has zero rest mass. This means that even under the theory of relativity, light does not gain mass as it travels. Understanding the principles of Special Relativity is crucial to grasping the nature of light. For further clarification, consulting resources on relativity is recommended.

Well, i am beginner with this topic. As the speed of particle increases its mass increases.thus i think that light emitted or radiated in form of wave and during propogation its velocity is high so it should behave as particle. Is it true and if not than what is true reason?

Your understanding of Special Relativity is faulty, and thus, your application of it is invalid.

Light has ZERO rest mass. Thus, even accepting the flaky concept of "relativistic mass", the relativistic mass of a "particle" that has zero rest mass is STILL zero!

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...
