# (a) Interpretation: Wavelength of first order and second order diffraction for an incident angle of 45° and reflection of 25° is to be determined. Concept introduction: Calculation of wavelength is done by using the following formula: m λ = d ( sin i + sin r ) Here, m= diffraction order λ= wavelength i = angle of incidence r = angle of reflection d = spacing ### Principles of Instrumental Analysis
