Question

My one 2. 0/50 points Previous Answers to determine the of 4 colorlines: Red, Yellow, Green and Violet The valestined are The following values were obtained using a spectroscope. Looking at a Hellum lam, the experimenter was shown in the table below or Space Resing (A( m wen obtained ). What is the equation of the ne? Tou use the values above to calibrate your spectroscope by placing a line of the range Spectroscope reading 619) and yellow (Spectroscope reading 587). You use the now calibrated spectroscope to view another unknown light source and are able to deter What are the corrected wavelengths for these two readings? Orange line Yellow Line Submit Answer

Answer 1

The given data is plotted and fitted to equation of line.

Corresponding slope(m) is =

1.15997

Intercept is =

-72.40207

Using these data, corrected wavelengths can be calculated

y=mx+c where y is corrected wavelength

"m" is slope

"C" is intercept and "x" is measured spectroscopic reading.

The detailed calculation is below
