SWBAT identify the different colors of the visible light and compare each of its frequency and wavelength.
How do we perceive colors?
-smallest part of the EM spectrum that the human eyes can see
Red to Violet (ROYGBIV)
Red – lowest energy, longest wavelength
Violet – highest energy, shortest wavelength
ROY G BIV
Which color has the most energy and short/small wavelength???
Violet the HIGHEST energy… and SHORT wavelength
Which color has the lowest energy and long/big wavelength???
Red the LOWEST energy… and LONG wavelength
What happens when you wear WHITE on a hot day?
How do we get white?
ALL the colors ROY G BIV being REFLECTED
What happens when you wear BLACK on a hot day?
How do we get black?
ALL colors of rainbow being ABSORBED.
4. How do we see color?
First, light goes from the source (sun, lamp, etc.) to the object.
