Why Isn't a Mirror the Same as a White Surface?

    Mirrors Surface
AI Thread Summary
A smooth white surface reflects light diffusely, scattering it in various directions, while a mirror reflects light specularly, maintaining the direction of the incoming light. This difference in reflection is due to the surface texture; mirrors are much smoother than white surfaces. Additionally, the discussion touches on the dual nature of light, explaining that photons are particles of light, while light also behaves as an electromagnetic wave. The confusion arises from trying to reconcile these two concepts, which represent different aspects of light. Understanding these principles clarifies why mirrors and white surfaces behave differently in terms of light reflection.

Hi,
I have a question,
If a smooth white surface reflects all light, then why isn't my mirror basically a white surface?
How come a white surface act as a mirror?

Also, I keep hearing about photons being light packets, but I heard that light is an electromagnetic wave, so how can I out the two together?

In my brain, I picture a light as a wave line pointing in one area, photons gives me a different picture of that.

A white surface reflects light in all directions (diffuse reflection), whereas a mirror reflects light in the same direction at every point (specular reflection). The white surface is not really that smooth.

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...
