Line Spectrum and Continuous Spectrum

Line Spectrum and Continuous Spectrum

A solid metal can be made by grouping several hot gaseous (monatomic) metals together. What is the difference between emission spectra in the gas (monatomic) and solid state? The simulation above is a simple example and … more

Photoelectric Effect Simulation

Photoelectric Effect Experiment

Photoelectric Effect The photoelectric effect is the phenomenon that the electrons pop out when a light beam incident on a metal surface. It can be thought that the energy of light is transformed into the form … more
