Sunsets
In what form does light travel?
In waves (NM also accepted)
Are gas molecules larger or smaller than light wavelengths?
Smaller
When we see a blue sky, we are seeing...
blue light scattering across the atmosphere
What color(s) have the shortest wave lengths?
Blue & Violet
What color(s) have the longest wave lengths?
Red & Orange
What determines how light interacts with the Earth's atmosphere?
(varying) amounts of energy
When colors are mixed, what color light do our eyes perceive it as?
White Light
What scatters sunlight across Earth's atmosphere?
Gas molecules
The upper part of the atmosphere absorbs what color?
The upper atmosphere absorbs violet light.
Why don't we see violet?
(1)The sun produces less violet light. (2)Our eyes are much better at detecting blue.
the shorter the wave of the blue light, the more the gas...
Scatters across the atmosphere
What does NM stand for in regards to wavelength?
nanometer
What is Rayleigh Scattering
the scattering of light by particles that are much smaller than the wavelength of the light.
Why does the sky appear red during sunset?
light is passing through more of the Earth’s atmosphere to reach us. So all the blue light gets scattered away before it reaches us and the red, orange, and yellow waves passes through. This is why sunsets often appear red even though the Sun itself isn't changing color.
Does yellow or green have a longer wavelength?
Yellow (600 NM to 500 NM)
