Diffraction Grating: in a Diffraction Grating Experiment, Light of 600

question 64

Multiple Choice

Diffraction grating: In a diffraction grating experiment, light of 600 nm wavelength produces a first-order maximum 0.350 mm from the central maximum on a distant screen. A second monochromatic source produces a third-order maximum 0.870 mm from the central maximum when it passes through the same diffraction grating. What is the wavelength of the light from the second source?

• A) 479 nm
• B) 497 nm
• C) 567 nm
• D) 749 nm
• E) 794 nm
