The sky is blue because of refraction. Sunsets and sunrise are so beautiful because of refraction. If there was no refraction, we would see the sky as a black expanse.
Due to refraction of light.
If someone says the sky is ashy, they are likely describing a dull or grayish appearance in the sky, often caused by pollution, smoke, or haze. It may indicate poor air quality or atmospheric conditions that affect visibility and color of the sky.
The sun
Yes, the word 'sunrise' is a noun, a singular, common, compound, concrete noun; a word for the first appearance of the sun in the sky each morning; the appearance of the sky when the sun first appears in the morning.
Rainbows get their colors from the reflection, refraction, and dispersion of light in water droplets. When sunlight passes through the droplets, the light is separated into its different colors, creating the rainbow effect we see in the sky.
Refraction of light allows for the change of appearance of an object
One possible explanation for the sudden appearance of purple lights in the sky could be the occurrence of a natural phenomenon such as an aurora borealis or a rare atmospheric event causing the refraction of light in a way that produces purple hues.
Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.

The index of refraction does not affect the frequency of light. Frequency is determined by the source of the light and remains constant as light travels through different mediums with varying indexes of refraction. The only property that is affected by the index of refraction is the speed of light.

It is a rainbow
It is a rainbow
The sky's blue color is caused by Rayleigh scattering, in which shorter blue wavelengths are scattered more than longer wavelengths by molecules and particles in the Earth's atmosphere. This results in blue light being dispersed in all directions, giving the sky its blue appearance.
this answer is rainbow. Thanks
