Question 3

Given: In Atomic Spectra lab, a student obtained his best-fitline equation to be y = 0.29 x + 46.8 when he plotted his Vernierreading on the y-axis and wavelength in nm on the x-axis.

Question: If the Vernier reading for a line is 185.4, what isthe predicted wavelength of this line in nm? (Keep 4 sig figs withone decimal place.)
