The specifications associated with a commercial spectrophotometer are: Diffraction grating with 600 groves per mm. Focal length, f, 370 mm. Blaze angle, first order, 500 nm. What is the reciprocal of the linear dispersion? Could the two emission lines of hydrogen, 656.28 nm and 656.10 nm be resolved to the base line with a slit width of 0.010mm? Note that the blaze angle is given in wavelength. Using the balze angle formula we can compute the corresponding angle
