Frequently asked questions

What wavelength is visible light?: Visible light spans roughly 380 nm (violet) to 700 nm (red). Green is around 550 nm with frequency ~545 THz.
Why is the speed of light fixed?: In vacuum, c is a fundamental constant (≈ 3 × 10⁸ m/s) by definition since 1983. In other media light slows down by a factor of the refractive index.
