Compare a double-slit prxc 2:-*s-* a-blz9vpdmf ia experim7sd9uo/4 bprk.t /svp ent for sound waves to that for light waves. Discuss the svtops4p7sk./b /9d u rimilarities and differences.
参考答案: Similarities
between doing a double-slit experiment with sound and light: the sources must be coherent for the
interference pattern to be observed; they both produce a pattern of high and
low intensity at some distance away from the double slit (bright and dark for
the light and loud and quiet for the sound); they both work best with a
single-frequency source. Differences
between doing a double-slit experiment with sound and light: The slits for light must be extremely close
together when compared to sound; you don’t actually need slits for sound (just
use two speakers).
