Colours and Light Frequency

Topic Content:

The reason why we see colours is because of emission spectra as they represent the specific wavelengths of light emitted by an atom or molecule when its electrons transition from a higher energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More state to a lower one, with each transition producing a distinct colour of light depending on its energy level; different elements have unique emission spectra, leading to different visible colours when excited.

When an electron falls from a higher energy level to a lower energy level, it
