NOTATION

Quantities in formulas

Wavelength is the distance between the nearest points of a wave in the same phase.
Speed is the speed and direction of change in body position.
A period is the time of one complete repetition of a process.
Frequency is the number of repetitions of a process per unit of time.
The speed of light in a vacuum is the maximum speed of propagation of interactions.
The wavelength in a medium is the spatial period of the wave inside the substance.
The refractive index is a characteristic of the retardation of light in a medium.
The grating period is the distance between adjacent lines of a diffraction grating.
Diffraction angle is the direction of the observed maximum relative to the original direction.
The order of the maximum is the number of the bright band in the diffraction pattern.
