The light’s spectrum records each wavelength’s intensity.3. Electromagnetic radiation is a mixture of radiation of different wavelengths and intensities.4. The full spectrum of the incoming radiation from an object determines the visual appearance of that object, including its perceived colour.5. When this radiation has a wavelength inside the human visibility range, that radiation is called light.
