Part C. If our eyes could see a slightly wider region of the electromagnetic spectrum, we would see a fifth line in the Balmer series emission spectrum. Calculate the wavelength, λ, associated with the fifth line.
Express your answer with the appropriate units.
Atoms give off light when heated or otherwise excited. The light emitted by excited atoms consists of only a few wavelengths, rather than a full rainbow of colors. When this light is passed through a prism, the result is a series of discrete lines separated by blank areas. The visible lines in the series of the hydrogen spectrum are caused by emission of energy accompanying the fall of an electron from the outer shells to the second shell. The wavelength (λlambda) of the lines can be calculated using the Balmer-Rydberg equation:
where mm is an integer, nn is an integer greater than mm, and R = 1.097 × 10 − 2 nm − 1 is the Rydberg constant.
