2 The wavelength is established as speeddivided by is the number of cycles persecond, or is considered to have both properties ofparticles and waves. The smallest quantum(unit) of light is a is light?White light is the combination of all of thecolour of the spectrum:RedOrangeYellowGreenBlueIndigoV ioletColourColour is subjective - we can only assumethat we each see the same who are colour blind perceive coloursacross a narrower range and cannot alwaysclearly differentiate between colours (mostcommonly between red and green).Colour andcolour temperatureColour temperature is a comparativemeasurement. A light source s colourtemperature is the temperature an idealblack-body radiator would reach to match thehue of the light in degrees Kelvin (the unit ofabsolute temperature), colour temperaturesabout 5,000 K are considered cool colours,while 2,700-3,200 K are considered andcolour temperatureDaylight on a clear day - over 5,000 KTungsten halogen - approximately 3,200 KIncandescent - approximately 2,700 KLux and lumenLumen is the measure of the amount of lightemitted per second by a light is a measure of lux = 1 lumen per square levels decrease as distance from the lightsource (or lights to you and me)Main types of luminaires.
