A.1) Use the sim to collect the line emission spectrum for hydrogen. Start by playing with the sim "Models of the Hydrogen Atom" Figure out how to do the following things with the sim: o Turn on the "gun" to direct light into a box of hydrogen. o Speed up, slow down, or pause the sim. o Use a spectrometer to detect photons emitted from the box. o Direct only green light (photons of "green") in to the box of hydrogen. o Direct only ultra-violet (UV) photons in to the box of hydrogen. o Collect the line emission spectrum using the spectrometer when white light enters the box. It may be helpful to speed up the sim. After a few minutes sketch the spectrum in the box below. Include in your sketch the colors (regions of the electromagnetic spectrum) and estimated wavelengths. o Also figure out how to take a picture of the spectrum. Save the spectrum on the screen. This is "experimental data" and can be compared with predicted line spectra for different atomic models
