Geometrical optics Light Mirror Perpendicular Reflection Tangent

AI Thread Summary

A tangent line touches a curved surface at a single point without crossing it, which is crucial in understanding reflections. When the angle of incidence is zero, the incident angle becomes 90 degrees, leading to no image formation. This situation highlights the unique properties of tangents in relation to curved surfaces. The discussion emphasizes the distinction between tangents and the behavior of light at reflective surfaces. Understanding these principles is essential for grasping the fundamentals of optics and reflection.

The tangent passes through just one point
Now i can draw it such that the angle of incidence is always 0 and incident angle is always 90
Then no image will be formed.
Why does this not happen??

A tangent passes through just one point of a curved line or surface, but does not cross it at that point. It doesn't sound as though you are talking about any curved surfaces.

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...
