Key concepts
3 concepts
- 1
The mnemonic roygbiv helps us remember the order of visible colors from lowest to highest frequency: red, orange, yellow, green, blue, indigo, and violet.
- 2
Reflection occurs when light bounces off a surface, with the angle of incidence being equal to the angle of reflection; refraction is the bending of light as it passes from one medium to another.
- 3
The additive primary colors are red, green, and blue, which can be combined to create white light; the subtractive primary colors are cyan, magenta, and yellow, which when combined create black.
