Crepuscular rays usually appear orange because the path through the atmosphere at dawn and dusk passes through up to 40 times as much air as rays from a high Sun at noon. Particles in the air scatter short-wavelength light (blue and green) through Rayleigh scattering much more strongly than longer-wavelength yellow and red light.
Gamma rays, at the high-frequency end of the spectrum, have the highest photon energies and the shortest wavelengths—much smaller than an atomic nucleus. Gamma rays, X-rays, and extreme ultraviolet rays are called ionizing radiation because their high photon energy is able to ionize atoms, causing chemical reactions. Longer-wavelength ...
An example of this phenomenon is when clean air scatters blue light more than red light, and so the midday sky appears blue (apart from the area around the Sun which appears white because the light is not scattered as much). The optical window is also referred to as the "visible window" because it overlaps the human visible response spectrum.

The flag with the off-set sun and 16 rays is the ensign of the Maritime Self-Defense Force, but it was modified with a different color red. The old flag is darker red (RGB #b12d3d) and the post-WW2 modified version is brighter red (RGB #bd0029). [22] The Imperial Japanese Army flag with symmetrical 16 rays and a 2:3 ratio was abolished.
"Yellow Light", by Pharrell Williams, created for the soundtrack of the 2017 film Despicable Me 3 "Yellow Light", by Of Monsters and Men on My Head Is an Animal
The phase velocity of light in a medium is commonly expressed using the index of refraction n, defined as the speed of light (in free space) divided by its speed in the medium. The difference in the refractive indices between the two circular polarizations quantifies the strength of the circular birefringence (polarization rotation),
The Emblem of Ethiopia has been in its current form since 1996. It contains a yellow interlaced pentagram radiating rays of light on a blue shield. Today, the pentagram stands for the unity of the people and nationality of the Federal Democratic Republic of Ethiopia.
