WebJul 3, 2024 · Astronomy researchers are often interested in the luminosity of an object, which is the measure of how much energy it puts out in the form of electromagnetic radiation. That tells them something about activity in … WebNote that we don't say that we see a beam of dust, though strictly speaking this is what reflects the light and hence is seen. I want to keep it in a simple way. Light is invisible because, there is no light striking the light (photons) and bouncing back to your eye. We don't 'see' photons, we 'detect' photons.

WebAug 26, 2024 · An object gets its color when electrons absorb energy from the light and become “excited” (raised to a state of increased energy). The excited electrons absorb certain wavelengths of light. What humans see is the complementary color of the absorbed wavelengths, i.e., the remaining wavelengths of light that are not absorbed. WebLight that is absorbed by an object is usually converted into heat energy. The goal of this project is to measure how much heat is produced by the absorption of light by different colors. You'll use an incandescent light (a heat lamp), and water-filled jars wrapped with different colors of construction paper.
