Light (and the electromagnetic spectrum). Electromagnetic Radiation is just a name for the range of radiation….(feel free to start singing) Light is both a particle and a wave Light particles are called photons (mass-less bundles of concentrated electromagnetic energy)

Wave Behavior. Interference Doppler Effect. Reflection Refraction Diffraction. Boundary Behavior. A sound wave travelling through water reflects off the submarine and returns to its original source. Does reflection of a wave affect the speed of the wave?
