35.6), the waves spread out from the slits as shown in Figure 37.1b. In other words, the light deviates from a straight-line path and enters the region that would other wise be shadowed. As noted in Section 35.3, this divergence of light from its initial line of travel is called diffraction. Inter ference in light waves from two sources was Ãrst demonstrated by Thomas Young in 1801.
