You have a diffraction grating with 3000 lines/cm. You also havea light source that emits light at 2 different wavelengths, 428 nmand 707 nm, at the same time. The screen for your experiment is 1.5meters from the diffraction grating.
A. What is the line spacing for the grating?
B. What is the difference in the angle of the 2nd bright fringefor each wavelength for this grating?
C. Which wavelength is closer to the center of the diffractionpattern?
D. How would the color separation be different if you used a1200 lines/cm grating? Explain.
E. What is the width of the central maximum for each wavelengthif the same light source is used to illuminate a single slit with awidth of 0.054 mm?
