This question is based on Lab 8, Flame Tests and Atomic Emission:

a. The Lyman series for atomic emission come from transitions of electrons in higher energy level relaxing to energy level 1. Use the Rydberg equation to calculate the wavelength of light if the electron in Hydrogen is initially in energy level 3. The Rydberg constant is 10,967,758 m-1 .

b. Perry O'tic wanted to look at the atomic emission spectrum of Helium. He created a spectroscope with a diffraction grating (4900 lines per cm) and two metersticks. The diffraction grating was located 23 cm from the optical slit. When Perry O'tic looked through the diffraction grating, he observed a spectral line 8.0 cm from the optical slit. What is the wavelength of the observed spectral line?

c. What part of the electromagnetic spectrum is the light from Part A? Part B?
