Answer to Question #216083 in General Chemistry for maya

Question #216083

Below is the energy level diagram (not drawn to scale) representing the transitions made by an electron in a hydrogen atom that result in the observed lines of both the absorption and emission spectra. Some are in the visible region, and some are not.

4 different energy photons are represented (approximate wavelengths are given in parentheses):

infrared (~ 10e-4 m)

red (~ 10e-6 m)

blue (~ 10e-7 m)

ultraviolet (~ 10e-8 m)

Match the transition (a - h) with the photon described (approximate wavelengths are given in parentheses.) Your answer input should be a single, lower case letter.

(Please note: This is not a problem for which a calculator is required. Your knowledge of the Bohr model of the atom and the relative energies of transitions is all that is needed.)

Blue photon emission (~ 10-7 m)

A photon (from the Greek "light") is an elementary particle, a quantum of electromagnetic radiation( in the narrow sense — light) in the form of transverse electromagnetic waves and a carrier of electromagnetic interaction. It is a massless particle that can exist only by moving at the speed of light. The electric charge of the photon is zero. A photon can only be in two spin states with a spin projection on the direction of motion (helicity) ±1. In physics, photons are denoted by the letter γ.
