Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Question

Two (and only two) full spectral orders can be seen on
either side of the central maximum when white light is sent
through a diffraction grating. What is the maximum
number of slits per cm for the grating?
