Problem 3: Passing an
electric current through an unknown gas produces several distinct
wavelengths of visible light. In this problem you will find the
wavelengths of the unknown spectrum by observing that they form
first-order maxima at angles of 23.9°, 30.2°, 35.5°,
and 41.4° when projected on a diffraction grating having
10,000 lines per centimeter.
Find wave length for each angle.
Problem 4: An electric
current through hydrogen gas produces several spectral lines from
the transitions to n = 2, called the Balmer
series. The four most visible ones are at 410.2 nm, 434.0 nm, 486.1
nm, and 656.3 nm. Assume you are observing these lines with a
diffraction grating of 4500 lines per centimeter.
What is the angle (in degrees) of the first-order maximum for
each wavelength?
