What is the wavelength of the new source

Reference no: EM13253817

When yellow sodium light, ?=589nm, falls on a diffraction grating, its first-order peak on a screen 55.0cm away falls 3.29cm from the central peak. Another source produces a line 3.67cm from the central peak.

A. What is the wavelength of the new source?

B. How many lines/cm are on the grating?
