3. Assuming the Sun is a perfect blackbody emitter with T = 5800 K, use Wien's displacement law to calculate the peak emission wavelength of the sun. What color does this wavelength correspond to (red, blue, green, etc.)?
Electronic Transitions and Spectroscopy
The term “electronic” connotes electron, and the term “transition” implies transformation. In a molecule, the electrons move from a lower to a higher energy state due to excitation. The two energy states, the ground state and the excited state are the lowest and the highest energy states, respectively. An energy change is observed with this transition, which depicts the various data related to the molecule.
Photoelectron Spectroscopy
Photoelectron spectroscopy (PES) is a part of experimental chemistry. It is a technique used in laboratories that involves projecting intense beams of radiation on a sample element. In response, the element ejects electrons for which the relative energies are measured.
According to Wien’s displacement law, the wavelength at which the intensity of radiation is maximum (λmax)for a blackbody radiating at absolute temperature T is given by,
λmax*T = b
Where b is weins displacement constant.
