Abstract In this experiment the goal is to measure the wavelength of light using diffraction grating. To study this technique the experimenter must know the principles diffraction, reflection, and transmission gratings. From these principles, the experimenter can determine the constructive interference of the waves using from the following formulas: d= 1/N and d sin θ n = n λ where n- 1, 2, 3 and etc. After the data is collected the sin θ, wavelength, and percent error were calculated. The number of grating lines was at 600 mm as the constant was at 1.63 x 10 -3 .; the percent error for data table 2 at first order and second order spectrum was about _____ percent difference in error. Need concluding statement for overall experiment. Introduction A diffraction grating consists of a large number of fine, evenly spaced parallel slits. There are two different types: transmission and reflection gratings.
