Could you use the spectroscope's calibration to determine the wavelenghts of emission lines that would be <400nm or >750nm (assuming that those lines would be visible to the human eye) ? Explain

Step 1
The visible spectrum for human eyes ranges approximately from 400 nm to 750 nm. Wavelengths below 400 nm fall into the ultraviolet range, and those above 750 nm fall into the infrared range. Show more…

When we use the flame test to provide insight on the colors of the photons emitted by specific electrons, we can correlate the colors back to the approximate wavelength of lines that would appear in the emission spectra. The downside to this approach it that it only works for lines that appear in the visible region. Would you be able to get more data from this test if your detector or camera could record ultraviolet light? What about gamma rays?

In the lab in person, students would use a spectroscope to measure the spectra of mercury in the labs fluorescent lights to calibrate the instrument for their lab group. This calibration process would allow you to determine how accurate the group is with your spectroscope. Here are the wavelength results for your hypothetical group's calibration: Student Wavelength for Line A Wavelength for Line B Wavelength for Line C Wavelength for Line D Wavelength for Line E (nm) (nm) (nm) (nm) (nm) Joe 435 495 545 576 614 Anna 440 497 548 580 616 Jia 431 491 549 581 612 All measurements have some degree of error. Consider the data recorded by your group for the emission spectrum of mercury. Which spectral line has the largest spread in recorded wavelengths? Select one: Line A Line B Line C Line D Line E
