Wave properties of electromagnetic radiation o Wave characteristics Frequency of a beam of radiation is determined by source and remains invariant, while velocity depends on the composition of the medium Power is energy that reaches a given area per second, while Intensity is power per unit solid angle These quantities are often used interchangeably These are related to square of amplitude o Superposition of waves Two waves with identical amplitudes but different frequencies produce a beat with period equal to the reciprocal of the frequency difference Fourier Transformation Any periodic function can be broken into its component sine and cosine waves o Diffraction of radiation Occurs when a parallel beam of radiation is bent as it passes by a sharp barrier or through a narrow opening When slit is wide relative to wavelength, diffraction is slight and hard to detect, but when slit is on same order of magnitude as wavelength, diffraction is observed
