To understand how a diffraction grating works; to understand the diffraction grating equation. ... Why is it necessary that the base side of the grating face toward the light source? Draw a ray diagram for the two cases: a) base toward the source (correct) and b) grating toward the source (incorrect).

All these waves interfere to produce the diffraction pattern. Consider a slit of width w as shown in the diagram below. ... For a diffraction grating with a large number of slits, the pattern is sharp because of the many positions of completely destructive interference between the bright, constructive-interference fringes.

In the diagram above, let's say that the light leaving the edge of the slit (ray 1) arrives at the screen half a wavelength out of phase with the light ... Such an array is known as a diffraction grating. The name is a bit misleading, because the structure in the pattern observed is dominated by interference effects.
