2 1. Why does the diffraction pattern appear only at specific locations when lightpasses through the grating?2. As the distanco botweon the diffraction feot gets narrower., the distance betwoenthe diffraction fringes (wider/narrower) becomes (wider/narrower) as the laserwavolength used becomes larger.
