Question - Part A- A radio station's channel, such as 100.7 FM or 92.3 FM, is actually its frequency in megahertz (MHz), where 1MHz=106Hz and 1Hz=1s?1.

Calculate the broadcast wavelength of the radio station 103.1 FM.

State your answer to four significant figures as well as include the appropriate units.

Part B- Green light has a frequency of about 6.00×1014s?1. What is the energy of green light?

State your answer to three significant figures as well as include the appropriate units.

Part C- Hospital X-ray generators emit X-rays with wavelength of about 15.0 nanometers (nm), where 1nm=10?9m. What is the energy of the X-rays?

State your answer to three significant figures as well as include the appropriate units.

Part D- An electron undergoes a transition from an initial (ni) to a final (nf ) energy state. The energies of the ni and nf energy states are ?2.420×10?19J and ?8.720×10?20 J, respectively.

Calculate the wavelength (?) of the light in nanometers (nm) corresponding to the energy change (?E) value of this transition. You can use the following values for your calculations:

Planck's constant (h)speed of light (c)1 m===6.626×10?34 J?s2.998×108 m/s109 nm

State your answer in nanometers to four significant figures.
Part E- An electron in the n=7 level of the hydrogen atom relaxes to a lower energy level, emitting light of 93.1 nm.

What is the value of n for the level to which the electron relaxed?

State your answer as an integer.
