SUMMARY
The discussion focuses on calculating the maximum visible wavelengths produced by a diffraction grating with 105 lines/m at an angle of 11°. The relevant equation used is d*sinθ = m*λ, where d is the grating spacing (1 x 10-5 m). The participants determined that for m values of 3 and 4, the corresponding wavelengths are 636 nm and 477 nm, respectively, indicating multiple solutions for visible wavelengths.
