About atmosphere light absorbtion

AI Thread Summary
The discussion addresses why the atmosphere and clouds are visible during the day but not at night, despite shining light into the sky. It highlights that the sun's light causes significant scattering, making the atmosphere and clouds visible during the day. At night, the scattered radiation is much less, resulting in reduced visibility. However, it is noted that clouds can still be seen at night if sufficient light is directed towards them, as demonstrated by examples like searchlights. Overall, the visibility of the atmosphere is primarily dependent on the intensity of scattered light.

Hi pf,

I am having a basic doubt.Even this may be a silly question.sorry for that.While in the morning due to sun's light we can able to see our atmosphere and also clouds.But at night even when we foccused a large amount of light towards the space. why can we able to see the atmosphere or clouds?why does the atmosphere not responding to the light at night?

"Clouds?" Yes. "Thin air?" No.

"Air" is transparent to visible light.

The amount of scattered radiation during the daytime when the sun is present is vastly greater than the amount of scattered radiation at night.

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...
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...
