Energy conversion

Learn about properties of harmonic waves.

λ = c ∕ ν		μm
ν = c ∕ λ		THz
k = 1 ∕ λ		cm-1
ω = 2πν		ps-1
E = h ⋅ ν		eV
τ = 1 ∕ ν		ps
T = E ∕ kB		K

λ - wavelength, ν - frequency, k - wavenumber, ω - angular frequency, E - photon energy, τ - oscillation period, T - equivalent temperature.

The Planck constant, h = 6.626070 ⋅ 10^-34 J⋅s = 4.13567 ⋅ 10^-15 eV⋅s

The speed of light in vacuum, c = 3⋅10⁸ m/s = 300 μm/ps.

The Boltzmann constant, k_B = 1.380649 ⋅ 10^-23 J/K.
