WebAbsorption occurs when photons from incident light hit atoms and molecules and cause them to vibrate. The more an object's molecules move and vibrate, the hotter it becomes. This heat is then emitted from the object as thermal energy. Some objects, such as darker colored objects, absorb more incident light energy than others. biography david hockneyWebX-rays are a form of electromagnetic radiation similar to radio waves, microwaves, visible light and gamma rays. X-ray photons are highly energetic and have enough energy to break up molecules and hence damage living cells. When X-rays hit a material some are absorbed and others pass through. Generally, the higher the energy the more X-rays ... daily care of chickensWebPower density is defined as power flow per unit area. For example, power density is commonly expressed in terms of watts per square meter (W/m 2 ), milliwatts per square centimeter (mW/cm 2 ), or microwatts per square centimeter (µW/cm 2 ). One mW/cm 2 equals 10 W/m 2, and 100 µW/cm 2 equal one W/m 2. daily care of clothesWeb10 de abr. de 2024 · Waves in the electromagnetic spectrum vary in size from very long radio waves that are the length of buildings to very short gamma-rays that are smaller than the nucleus of an atom.
