Spectroscopy

Two formulas are required for spectroscopy.

$c = \lambda v$

$c = 3 \times 10^8 \text{ m/s}$
$\lambda = \text{ wavelength (m)}$
$v = \text{ frequency(s^-1 or Hz)}$

$E = hv$

$E = \text{ Energy per Quantum (J)}$¹⁾
$h = 6.63 \times 10^-34 \text{ Js}$²⁾
$v = \text{ frequency(s^-1 or Hz)}$

quantums here are photons
