Visible Light Definition
It's the range of electromagnetic waves that can be detected by the human eye.
Red is the weakest and violet is the strongest
When the white light hits the prism it changes into a rainbow.
Each color has a different wavelenght
The red color has a more spaced out wavelength when the violet has a more close together wavelength.
In this picture, the sun is hitting the ground and it absorbs all of the colors expect green and it bounces off and hits our eyes.
That is why its best to wear white in the summer because it reflexes all color. And black absorbs all color.
Each color has a different frequency.
Wavelength and Frequency
Wavelength- 750 nm- 400 nm
Frequency- 4x10 14 - 7.5x10 14 Hz
Uses For Visible Light
- To see things
- Laser printers
- DVD players
- weapon aiming systems
Did You Know...
- As objects grow hotter, they radiate energy dominated by shorter wavelengths, changing color before our eyes.
- Too much light can damage the retina in your eye
