Quantum mechanical model of an atom

How did Einstein explain the photoelectric effect?

posted on May 12, 2019

Back then (in the 1900s) scientists saw that when light of certain frequency and energy shines on a light sensitive (photosensitive) metal, the metal emitted electrons, generating an electric current …

How Bohr explanation of the hydrogen line emission spectrum led to the quantum mechanical model of the atom

posted on May 8, 2019

A spectrum is the ‘picture’ you get when light interacts with atoms or molecules. A spectrum is usually a plot of how much light is absorbed or emitted versus the wavelength or frequency of light. For …
