Experiment Thirteen s Law and Spectrophotometry Prelaboratory Quiz Name Laboratory Section According to Planck's equation, the energy ofa monochromatic igh depends only on its is elevated from a- Since electronic states in n electron in a molecule, atom or ion, in which the electron 2. electronic stat to a , state. ecules or ions are quantized, absorption of quanta occurs a ions are 3. a characteristic on the number of electrons that undergo the electronic transitio Beer-Lambert's law states that 4. The amount of light (or the number of photons) absorbed depends, amone ohc other things, 4 on the optical path and the n. In a solution, this of the solution. S. lo = the intensity oflight before absorption, I - the intensity of light after absorption, l- the optical path (length of absorbing solution) where the molar concentration of solution = molar extinction coefficient (a value unique to the solution. Take the logarithm of the equation on both sides, and show that 85

Explanation / Answer

1) frequency

Planck equation is given as  E = hf. Here, E is the energy of each packet (or 'quanta') of light, measured in Joules; f is the frequency of light, measured in hertz; and h is Planck'sconstant.

2)ground,excited

The energy conferred to the electron pushes it from the ground state to an excited high energy state(imagine a rocket getting fuelled up)

3)frequencies

4) concentration
