Dear all,
A beam of parrllel light of wavelength 450 nm is incident normally on a diffraction grating with 6000 lines peer cm. Would u give me some idea how to find the maximum number of orders of diffraction thact can be seen on each side of the central (zeroth order) maximuum of the far side of the grating ??
this question only provide the wavelength and the d ! how about the angle ?? Have i need to find the angle first ?? and how to find ??
