Document Summary

Purpose: to determine the grating constant and rulings of a diffraction grating. Violet: d = m i= (1)(447. 2nm) sin sin15. 5o. Blue: d = m i= (2)(471. 3nm) sin sin16. 3o. Green 2: d = m i= (3)(492. 2nm) sin sin17. 0o. Green 1: d = m i= (4)(501. 57nm) sin sin17. 5o. Yellow: d = m i= (5)(587. 56nm) sin sin20. 6o. Red 2: d = m i= (6)(667. 81nm) sin sin23. 6o. Red 1: d = m i= (7)(706. 52nm) sin sin25. 1o. Violet: d = m i= (1)(447. 2nm) sin sin15. 8o. Blue: d = m i= (2)(471. 3nm) sin sin16. 7o. Green 2: d = m i= (3)(492. 2nm) sin sin17. 5o. Green 1: d = m i= (4)(501. 57nm) sin sin17. 8o. Yellow: d = m i= (5)(587. 56nm) sin sin20. 9o. Red 2: d = m i= (6)(667. 81nm) sin sin23. 7o. Red 1: d = m i= (7)(706. 52nm) sin sin25. 3o. = -9718. 87 m ruling d = 1 i d. Possible sources of errors for this experiment are:
