What kind of light or lamp should I use for a science fair experiment on heat absorption? - white and black wrapping paper
The experiment used containers filled with water, each equipped with a thermometer. The pots are wrapped in paper ... white, gray and black. The temperature is measured over time. Appears to be a "sun causes" on the list of materials, but I'm not sure if this is better for the change of the angle (where the constant) and where you get to.
Thoughts and ideas about the things that I observe?

White And Black Wrapping Paper What Kind Of Light Or Lamp Should I Use For A Science Fair Experiment On Heat Absorption?

I think the halogen light can be a good idea. The heat lamps, but they are designed for a variety of infrared, and some (not all absorption) of dyes are very different in the infrared. I have the infrared viewers in dark rooms for photography and some things that are dark in visible light is very bright in the infrared. If you're unlucky, that their role was a black color, it could ruin the results. Although substantial halogens also emit infrared light, have a higher percentage of visible light with a heat lamp.
ReplyDeleteAll high-power light bulbs should be good, or a sun lamp or incandescent reflector. You can buy a coat with a large clip (for easy assembly, in which it is) at The Home Depot, Lowes, Walmart or any hardware store. To ensure good quality data are recorded to show that light, you are far enough from the pitchers that the light has no influence radiates heat to the temperature of the glasses. In addition, cut situated a gate with a 1-2 "diameter holes between the light source and lenses, to ensure that only the energy measured amplification of the light absortion on the materials. Requires that d" light and a barrier to Measure the gain at a time, but make sure that their environment, and the same are measured and recorded.
ReplyDeletewith a halogen lamp as a heat lamp for a lizard cage or something to ensure you get the heat transfer. You can find almost any pet shop too:) Good luck!
ReplyDeleteKeep it simple and inexpensive. Use light bulbs. They put a lot of infrared.
