why is the sky blue?

Question

discuss the wavelength of light, the reflection by molecules in the atmosphere , and what happens to the other colors.

Answer 1

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Combined, these effects scatter (bend away in all directions) some short, blue light waves while allowing almost all longer, red light waves to pass straight through. When we look toward a part of the sky not near the sun, the blue color we see is blue light waves scattered down toward us from the white sunlight passing through the air overhead. Near sunrise and sunset, most of the light we see comes in nearly tangent to the Earth's surface, so that the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red.

Scattering and absorption are major causes of the attenuation of radiation by the atmosphere. Scattering varies as a function of the ratio of the particle diameter to the wavelength of the radiation. When this ratio is less than about one-tenth, Rayleigh scattering occurs in which the scattering coefficient varies inversely as the fourth power of the wavelength. At larger values of the ratio of particle diameter to wavelength, the scattering varies in a complex fashion described, for spherical particles, by the Mie theory; at a ratio of the order of 10, the laws of geometric optics begin to apply.

Answer 2

because the sunlight refracted in the atmosphere absorbs all the other visible color wavelengths (Red, Orange, Yellow, Green Indigo, Violet), and only the blue wavelength is refracted through. So we see blue When the sun sets (or rises) so that the rays are at a different angle, we see the other colors in the sunrise/sunset..

Answer 3

Because if it was green, people wouldn't know when to stop cutting the grass.
