Blue pigment reflects not only blue light, but also colors to either side of blue namely, green and violet. It absorbs red orange and yellow light.
Red , orange, and yellow have been subtracted from the incident light.
Nitrogen and oxygen molecules ring like tiny bells with high frequency when energized by sunlight.
Reemit light in all directions like the sound of a bell.
Ultraviolet light from the sun is absorbed by the protective layer of the ozone gas.
Visible frequencies of violet light is scattered.
Although the violet light is scattered more, our eyes are only sensitive to blue. That’s why we see a blue sky.
Lower frequencies of light are scattered the least by nitrogen and oxygen molecules
Red, orange, yellow are transmitted more readily through the atmosphere
Light of lower frequencies is transmitted while light of higher frequencies are scattered
At dawn and sunset, the sunlight reaches the earth at a longer path
At noon, the light travels the least
Blue light is scattered as the path of the sunlight becomes longer
Water is transparent to almost all the visible frequencies of light.
The color is actually the reflected color of the sky
Red is absorbed by the molecules in the water
Every element has its own specific glow
The light from the elements can be analyzed by a spectroscope
It is composed of thin slits, lenses, and a prism
It displays the spectrum of light
Line spectrum- images of the slit through which the light passes
