Light in Photography -   Visible radiation

Light - lies in the narrow band of wavelengths from roughly 400 to 700 nm. One nanometer is 10-9 or one millionth of a millimeter. Within this range, the wavelength determines the colour of the light we perceive, beginning with violet at the shortest wavelengths and proceeding through blue, green, yellow and red.

Beyond the red end of the visible spectrum lies the invisible infra red region and wavelengths shorter than violet are called ultra-violet, also invisible. Remember that while we only see light - film and some digital cameras are capable of recording UV and Infrared- we even have X Ray film - so it is important to remember that what we see and what the camera records might be different.

Light travels through space at 186,000 miles a second and it takes 8 mins for the light of the sun to reach the earth.

I worked on a project titled @ the Speed of light.
