WebPotassium is usually measured at 766.5 nm, the most sensitive wavelength [13]. What does potassium look like? Potassium is metallic and silvery white. It is soft, waxy and can … Web15 Aug 2024 · Each of these jumps involves a specific amount of energy being released as light energy, and each corresponds to a particular wavelength (or frequency). As a result of all these jumps, a spectrum of lines will be produced, some of which will be in the visible part of the spectrum.

WebWhat is the emission spectrum of sodium? The sodium spectrum is dominated by the bright doublet known as the Sodium D-lines at 588.9950 and 589.5924 nanometers. From the energy level diagram it can be seen that these lines are emitted in a transition from the 3p to the 3s levels. The line at 589.0 has twice the intensity of the line at 589.6 nm. Web22 Feb 2016 · The work function of potassium is 2.26 eV. Therefore a light wavelength must be at least 2.26 times 1.6 times 10 to the negative 19th power J to remove electrons. … merci thais
