Compare a double-slit expe(lzoim dvc cf*s+5c83rimentp3u:v -es 2r5mzzwmwsb:: )qb for sound waves to that for light waves. Discuss the similarities and dif5r wpwmzbv 2u::3zq)bsm- e: sferences.
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).
