WebSep 12, 2024 · Well, the short answer for this is because the molecules of our atmosphere, like the nitrogen molecules or the oxygen molecules, tend to scatter blue light more than red. So let's explore this in a little bit more detail. We've talked about scattering of light in previous videos. WebMar 30, 2024 · The diffraction grating reflects the photons at a different angle. So there is no such thing as a red or blue photon because it matters how fast the thing it hits is moving. The thing it hits will see it as red or blue, and something else would see it differently. But again, this is counter-intuitive.
