Problem: Cesium was discovered in natural mineral waters in 1860 by R. W. Bunsen and G. R. Kirchhoff, using the spectroscope they invented in 1859. The name came from the Latin caesius (“sky blue”) because of the prominent blue line observed for this element at 455.5 nm. Calculate the frequency and energy of a photon of this light.

FREE Expert Solution

Recall: The energy of a photon is given by the equation:

where h = Planck's constant and v = frequency of light. Frequency and wavelength (λ) are related via the following equation:

where c = speed of light (3.00 x 108 m/s).
