KEY CONNECTIONS

Formulas

ν = \frac{n}{t}

ν = n / t

ν = \frac{1}{T}

ν = 1 / T

ν = \frac{v}{λ}

ν = v / λ

ν = \frac{c}{λ}

ν = c / λ

E = h ν

E = hν

NOTATION

$\nu$: Frequency is the number of repetitions of a process per unit of time.
$n$: The number of cycles is the number of complete repetitions of the process.
$t$: Time is a quantity characterizing the duration and sequence of events.
$T$: A period is the time of one complete repetition of a process.
$v$: Speed is the speed and direction of change in body position.
$\lambda$: Wavelength is the distance between the nearest points of a wave in the same phase.
$c$: The speed of light in a vacuum is the maximum speed of propagation of interactions.
$E$: Photon energy is the energy of an individual quantum of electromagnetic radiation.
$h$: Planck's constant is the coefficient of connection between quantum energy and frequency.
