Waves and Energy
... Scientists knew that the wave model could not explain a phenomenon called the photoelectric effect. In the photoelectric effect, electrons are emitted from a metal's surface when light of a certain frequency shines on the surface. In explaining the photoelectric effect, Albert Einstein proposed that ...

... A compound is made up of two or more elements or two or more types of atoms, chemically combined and therefore exists as molecules. Examples of compounds are water, H2O; sulfuric acid, H2SO4; carbon monoxide, CO.. Although there are two or more different types of atoms present, it is important to re ...
