 Electromagnetic Radiation This includes different types of light such as visible light, x-rays, microwaves, gamma waves, radio waves, etc Energy in light behaves like waves. This version of classification led us to understand that light can behave like a wave. Wave Nature of Light Decided by the variables of frequency and wavelength Frequency and Wavelength are closely related and depend on each other Frequency The number of cycles the wave undergoes per second v (nu); expressed in hertz Wavelength The distance between any point on a wave and the corresponding point on the next crest/trough of the wave; the distance the wave travels during once cycle, expressed in meters or angstroms (10^-10 meters) Speed of Light A constant equivalent to 3.00 x 10^8 m/s in a vacuum expressed as c Speed of a Wave The distance traveled per the unit of time - describes the velocity c = wavelength x frequency Amplitude A height of a crest or a depth of a trough - was THOUGHT to be a measure of the intensity of light, which we perceived as brightness A = amplitude Electromagnetic Spectrum Continual radiant energy; different parts utilized for specific uses All waves in the spectrum travel at the same speed through a vacuum, but differ in wavelength and frequency Monochromatic Light Light of a single wavelength/frequency One single color Polychromatic Light Light of multiple wavelengths/frequencies White light; most of the light we see is this
