The sunlight that we see is a type of electromagnetic radiation that is emitted by the Sun. Known as the visible light, it looks white but is composed of colors of different wavelengths, with violet having the shortest wavelength and red having the longest. You can see the different colors when you look through a prism or … See more The Earth’s atmosphere is primarily made up of gas molecules, with oxygen comprising about 21% and nitrogen about 78%. In addition, water molecules in the form of droplets, ice crystals, and vapor, and particles such as … See more When sunlight strikes gas molecules, such as nitrogen and oxygen, light of longer wavelengths, like red, yellow, and orange, easily passes through, while light of shorter wavelengths, … See more The quality of the air that sunlight has to pass through also has an effect on the color of sunrises and sunsets. Dust particles and pollutants tend to tone down the colors in the skyas well as impede light from reaching the … See more During sunsets and sunrises, when the Sun is closer to the horizon, sunlight has to travel through a longer distanceand more of the dense environment to reach an observer’s eye. … See more WebThe Rayleigh criterion shows that the minimum angular spread that can be resolved by an image forming system is limited by diffraction to the ratio of the wavelength of the waves to the aperture width. ... whereas the red circle shows that the human eye should have a resolving power of 20 arcsecs in theory, though normally only 60 ...

WebRayleigh scattering theory is reasoned for the red colour of the sun in the morning and the blue colour of the sky. Let p be considered as the probability of scattering and λ is the wavelength of radiation, then it is … WebIf we take the intensity of scattered violet light at the 400nm limit of visibility to be 100, then red light at 700 nm is scattered only at an intensity of 10.7. Blue is much more strongly scattered than red. The terms "Rayleigh scattering" and "Tyndall blue" are often applied to scattered blue light.
