NOTATION

: Frequency is the number of repetitions of a process per unit of time.
: The number of cycles is the number of complete repetitions of the process.
: Time is a quantity characterizing the duration and sequence of events.
: A period is the time of one complete repetition of a process.
: Speed is the speed and direction of change in body position.
: Wavelength is the distance between the nearest points of a wave in the same phase.
: The speed of light in a vacuum is the maximum speed of propagation of interactions.
: Photon energy is the energy of an individual quantum of electromagnetic radiation.
: Planck's constant is the coefficient of connection between quantum energy and frequency.
