If there is a temperature of light,does a can you cold light ray exist?
Light should be near absolute zero seeing as it is massless. Absolute zero = -273 degrees Celcius Edit: Wait that was a dumb thing for me to say... because if light were actually -273 degrees we would all be frozen to death. In fact, we wouldn't be here in the first place. So I don't know the answer.
I disagree, light is made up of packets or quanta of photons. They do have a mass however small it may be. Since they are particles they must vibrate at a certain frequency and vibrations of particles denotes heat (however small it may be). Cold is also a relative term. Cold compared to what. As it was stated, it cannot be colder than absolute zero because at that temperature, particles cease all movement. So no, there cannot be a cold light ray.
The lights have the temperature when they work, but i think the LED lights is a better choice to prevent high temperature cause.
Light itself has no temperature as temperature is an indirect measure of how energetic particles are - light has no particles Light is a wave - it can carry energy, so cause another object to heat up - where the confusion can occur - hot sunlight vs. cold sunlight, but that is not the light wave, just its intensity - and therefore the energy it imparts
