The Development of a New Atomic Model

1. The Wave Description of Light

   • Visible light is a type of electromagnetic radiation = a form of energy that exhibits wavelike behavior as it travels through space.
     • examples of electromagnetic radiation: x-rays, ultraviolet and infrared light, microwaves, and radio waves
       • all forms of electromagnetic radiation together form the electromagnetic spectrum
         • all forms of electromagnetic radiation move at a constant speed of 3.00 X 10^8 meters per second (m/s).
   • Wavelength
     • the distance between corresponding points on adjacent waves.
       • the unit for wavelength is a distance unit. Depending on the type of electromagnetic radiation, it can be expressed in meters, centimeters, or nanometers.
