Transcript of Period 7 Larkin

Why is the sky blue?
Blue spreads across the sky in a bigger amount than other colors, when light from the sun cruises into the atmosphere. The dispersed light is what makes the sky blue.
Light Waves
Each color in a wavelength goes with a different frequency and a wavelength of light. A color is spread out more by the atmosphere if the wavelength is shorter. Blue has less long of a wavelength than red so the blue wavelength is spread out ten times more than a red wavelength. Visible solar radiation has many wavelengths and is strongest at 0.5 micrometers, which is blue. When this wavelength spreads, it is dominant and the sky looks blue. The deeper the a color will be if you go higher in altitude. By their non-similar wavelengths, colors of light are noticeable. Unless there's an obstacle, light travels in a straight line. If something did get in the way of the light like something that reflects it, like a mirror or bend the wavelength like a prism. Light waves that are short look blue. The sky will turn gray and all of the light from the sun will spread if the sky is full of smoke or dense clouds.
The Sun and Molecules
White light of all colors: red, orange, yellow, green, blue, indigo, and purple is what the sun makes. According to their frequency: red, orange, and yellow have a lower frequency than violet, indigo and blue light. A dominant yellow-orange hue is left to the transmitted light when the blue light scatters. By small molecules of air in Earth's atmosphere, blue light is scattered in different ways. Gas molecules in the atmosphere is what makes blue light spread. Blue light scatters more than other colors because of nitrogen molecules.
White light, that comes from the sun is made up of all colors.
The sun sends out wavelengths that are different lengths and different colors.
