Frequently Asked Questions
What is the relationship between frequency and wavelength?
For electromagnetic waves, frequency and wavelength are inversely proportional: as frequency increases, wavelength decreases. They are related by c = fλ, where c is the speed of light.
What is the visible light spectrum range?
Visible light has wavelengths from about 380 nm (violet) to 700 nm (red), corresponding to frequencies from about 430 THz to 790 THz.
