In this lab you will use a spectrometer to measure the wavelengths of several visible lines emitted from hydrogen gas, a. k.a. the balmer series. sketch and label an energy level diagram for hydrogen, and draw the transitions corresponding to the first four lines in the balmer series (nf = 2). for the first four lines, indicate which is toward the red end of the spectrum and which is toward the purple end. 2. [caution: tricky! ] equation 1 predicts the relationship between ! and ni for hydrogen. unfortunately, it is not linear. linearize the equation: that is, propose a function of ! that can be the y variable and a function of ni that is the x variable. graph your linear function and label your axes. indicate how to find eh and nf from the slope and/or intercept of this linear fit. (note: this will be a key component of what you will be asked to do in the lab, so make sure to spend plenty of time working this through to save yourself some time during lab! )
