Edmonds Community C/ XyDlabs o winter2018.pdf × . ab5-Winter2018%20(1).pdf omen the background-ncardecent Tight w m appear in photographs or rear pec ra. Figure 3 shows images of real spectra for each of the elements included in the interactive lab. Your job will be to identify each and the peak intensity wavelength, ak, of each element. To identify the peak wavelength, look at the plot on the lower left screen and click on the largest peak. Some elements will have more than one peak wavelength. If this happens, list them both in Table 2.

Explanation / Answer

A corresponds to hydrogen with a peak wavelength of 660 namometer corresponds to red colour.

B corresponds to Neon as it has a peak of 580-590 nanometer and this also have the most dispersion of light while passing through the prism.

C corresponds to sodium with a peak wavelength of 590 namometer. As it mostly emit the radiation in the wavelength of yellow colour.

D corresponds to mercury with a peak wavelength of 405 namometer and 435 namometer.

Helium is E which corresponds to 590 namometer’s peak Wavelength, which gives yellow colour.
