Confusion Light

AI Thread Summary

The discussion centers on the secondary refraction of light in rainbows, specifically addressing the angles at which red and violet light refract. It clarifies that in a secondary rainbow, the angles differ from the primary rainbow, with red light refracting at approximately 50 degrees and violet at about 40 degrees. Participants emphasize the importance of distinguishing between primary and secondary rainbows when discussing refraction angles. A hyperlink is provided for further details on the specific angles involved. Understanding these nuances is crucial for accurately interpreting the phenomenon of double refraction in secondary rainbows.

what really happens in the secondary refraction of light in a rainbow when it occurs ?
Do red and violet stil refract at an angle of 42 and 40 ?

If you mean the secondary rainbow (not refraction), then no, the angles are different.

sry, i meant the about the double refraction in a secondary raibow.And do tell me what the change in angles are.

Just click the hyperlink in my last post to get the angles of the secondary rainbow.

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...

Thread 'The focal length of the eye and image inversion'

After my surgery this year, gas remained in my eye for a while. The light air bubbles appeared to sink to the bottom, and I realized that the brain was processing the information to invert the up/down/left/right image transferred to the retina. I have a question about optics and ophthalmology. Does the inversion of the image transferred to the retina depend on the position of the intraocular focal point of the lens of the eye? For example, in people with farsightedness, the focal point is...
