Key concepts
3 concepts
- 1
The mnemonic roygbiv helps us remember the order of visible colors from lowest to highest frequency.
- 2
When light is reflected, the angle of incidence and the angle of reflection are equal, but when light is refracted, the angle changes as it passes through different mediums.
- 3
The additive primary colors are red, green, and blue, and when combined, they produce white light.
