Problem: Using a diffraction grating that has 1000 lines per centimeter, two other lines in the first-order hydrogen spectrum are found at angles of 4.85 x 10-2 rad and 6.58 x 10-2 rad.
Part A: What are the wavelengths of these lines?
...... nm (lower wavelength)
...... nm (higher wavelength)
Please explain how you came to your conclusion for above problem.
