The hydrogen spectrum shows 4 lines in the region visible spectral (this series is called the Balmer series: Hα (red): λ= 656.3 nm, Hβ (blue-green): λ = 481.1 nm, Hγ (purple): λ = 434.1 nm, and Hλ (purple): λ = 410.2 nm). Another series in the hydrogen spectrum is the Lyman series. Determine the wavelength of the second line of the Lyman series in m and nm (give two digits after the decimal point).

Problem: When alpha-iron is subjected to an atmosphere of hydrogen gas, the concentration of hydrogen in the iron, CH (in weight percent), is a function of hydrogen pressure, PH2 (in Mpa), and asbsolute temperature (T) according to CH= 1.34 X 10-2 sqrt(PH2) exp(- (27.2KJ/mol) / RT) Consider a thin iron membrane with the thickness and temperature listed below. Calculate the flux in (kg/(m2-s)) through this membrane if the hydrogen pressure on one side of the membrane is 0.17 MPa, and...

Consider a binary star system that has bright lines at 656.72 and 656.86 nm. Over the course of six months the 656.72-nm line moves to longer wavelength and the 656.86-nm line moves to shorter wavelength, until finally the two have swapped (i.e., the spectrum of the star system again shows bright lines at 656.72 and 656.86 nm). Assume that the stars are of roughly equal mass and moving in a circular orbit with axis perpendicular to the line connecting the...
