Enhancement of Microscopy
Microscopy helps us view objects that cannot be seen with the naked eye.
The Spectrometer
A spectrometer uses properties of light to identify atoms by measuring wavelength and frequency, which are functions of radiated energy.
The Michelson Interferometer
The Michelson interferometer is the most common configuration for optical interferometry.
LCDs
Liquid crystal displays use liquid crystals which do not emit light, but use the light modulating properties of the crystals.
Using Interference to Read CDs and DVDs
Optical discs are digital storing media read in an optical disc drive using laser beam.
