A diffraction grating is made with 600 lines per millimeter is illuminated with violet light of wave length 400nm.

(a) How many lines can be observed with this grating? 

(b) If the intense white light is incident on the same diffraction grating and the grating to screen distance is 2.75 m, find the distance on the screen between the 2^nd  order violet (400 nm) and 2^nd order red (700 nm) light.
