I also used 3 bottles of water and 1 special thermometer which measured two at a time by using long cords. After I got my materials, I first put the cords inside the blue and red transparent colored paper covered water and started looking at the thermometer. It was going up and up. I also took pictures using a phone. Then, I did it on red and green exceptthat there was something wrong with the camera. I then got the results but in fahrenheit so I calculated and got the desired results of temperature. The red heated up the water by 0.2 and blue and green both heated up by 0.3. The blue is higher by 0.07 to green. My hypothesis is correct. |
Hello my name is Martin Liu and today I’m going to present on which color of visible light is best used for heating. I noticed that the sun’s rays are powerful at heating thing so I thought of this experiment, which heats water the most out of the red, green, and blue after two minutes? I am doing this experiment for knowledge and possibly finding a way how to heat water. I hypothesize that blue light is used best. I couldn’t find colored lights so I used same brand colored transparent binder dividers. |

You all know that black objects heat up the most when in contact with light, but which light heats the greatest? Light constantly gets reflected and absorbed. Everything reflects or absorbs light except white or black objects. Objects create color when they reflect light. Objects get energy when they absorb light. Objects absorb the inverse of what it reflects. |
Because of studies and complex equations such asE=hc/ the hottest visible light is violet (not purple on the diagram because of supernumerary rainbows cause purple) and the hottest invisible lights are cosmic rays that makes quark gluon plasma and is about planck temperature, a quantum limit of temperature. |
