Filters also work by using the subtractive theory Filters contain pigments. As light is transmitted through the filter, these pigments absorb some light colours but not all. Example: A blue filter absorbs red and green light, and transmits blue light. Filters and Subtractive Theory What light co...

The Electromagnetic Spectrum and Sources of Light The Spectrum of Visible Light • The light that comes from the Sun or a source like a candle is called visible light. It is the light that is visible to the human eye. • Over 300 years ago, Sir Isaac Newton passed visible light ...
The Electromagnetic Spectrum Wavelength alone distinguishes types of light Visible light covers a tiny range of possible wavelengths We have used technology to make other wavelengths “visible” defining, in the process new regions of the spectrum. Radio, Infrared, Visible, Ultraviolet, X-ray, and G...
