$LMEC-15 Interference, Diffraction and Velocity Measurement of Sound Wave$

LMEC-15 Kupindirana, Kusiyanisa uye Velocity Kuyera kweRuzha Wave

Tsananguro Pfupi:

Chigadzirwa Chigadzirwa

Chigadzirwa Mateki

Ongorora: oscilloscope haina kuiswa

Mune anoshanda mafomu, kuyerwa kweiyo ultrasonic yekuparadzira velocity yakakosha mukuyera kweiyo ultrasonic inotenderera, kumisikidza, mvura kuyerera velocity, zvinhu elastic elastic modulus uye pakarepo pakarepo tembiricha yegasi. Ruzha kumhanya kuyerwa nzwisisika yekuyedza chiridzwa chakaburitswa nekambani yedu chishandiso chakawanda chekuyedza. Iyo haingogone chete kucherechedza chinoshamisa chekumira kwemasaisai uye kudonhedzwa kwemavhezheni, kuyera kupararira kwekutenderera kwezwi mumhepo, asi zvakare kuona zvakapetwa zvakapetwa kaviri uye kupatsanurwa kumwe chete kwenzwi reruzha, kuyera kureba kwezwi rekurira mumhepo, tarisa kupindira kuri pakati pekutanga kwemafungu uye kuratidzwa kwemasaisai, nezvimwewo. Kuburikidza nekuyedza, vadzidzi vanogona kugona misimboti uye nzira dzekuyedza dzedzidziso yemafungu.

Kuedza

1. Gadzira uye gamuchira ultrasound

2. Kuyera inzwi velocity mumhepo uchishandisa phase uye resonance kupindira nzira

3. Dzidza kupindira kwekuratidzwa uye kwekutanga kwezwi ruzha, kureva ruzha wave "LLoyd girazi" kuedza

4. Cherekedza uye chiyera zvakapetwa zvakapetwa-kaviri uye imwe-yakatemwa musiyano wezwi reruzha

Zvikamu uye Magadzirirwo
