A transparent diffraction grating has a period `d = 1.50mum`. Find the angular disperison `D` (in angular minutes per nanometers) corresponding to the maximum of highest order for a spectral line of wavelength `lambda = 530mm` of light falling on the grating  (a) at right angles, (b) at the angle `theta_(0) = 45^(@)` to the normal.
