How many orders will be visible if the wavelength of the incident radiation is 5000 Å and the number of lines on the grating is 101319 per metre.
Given : d = \(\cfrac1{101319}\) λ = 5000 x 10-10 m λ = 5 x 10-7 m using d sin θ = nλ θ = 90° d = nλ n = \(\cfrac{d}λ\) = \(\cfrac1{5\times10^{-7}}\) x \(\cfrac1{101319}\) n = \(\cfrac{10000000}{506595}\) = 19.73
