Study Notes
Electromagnetic Radiation and Human Perception
- Electromagnetic radiation in the range of wavelengths is called visible light.
- A typical human eye responds to wavelengths from approximately 380 to 750 nanometers (nm).
- These boundaries are not sharply defined and may vary per individual.
- Under optimal conditions, the limits of human perception can extend to 310 nm (ultraviolet) and 1100 nm (near infrared).
- The optical spectrum is sometimes considered to be the same as the visible spectrum.
- The term "optical spectrum" can be defined more broadly to include ultraviolet and infrared parts of the electromagnetic spectrum.
- In terms of frequency, human perception corresponds to a band in the vicinity of 400-790 terahertz (THz).
