$Ukuphazamiseka kwe-LMEC-15, ukuDifraction kunye neVelocity Ukulinganiswa kweWave yeSandi Umfanekiso oFakiweyo$

$Ukuphazamiseka, ukuDifraction kunye nokulinganiswa kwesantya seWave yeSandi (LMEC-15)$

Ukuphazamiseka, ukuDifraction kunye nokulinganiswa kwesantya seWave yeSandi (LMEC-15)

Inkcazo emfutshane:

Qaphela: i-oscilloscope ayifakwanga

Kwizicelo ezisebenzayo, ukulinganiswa kwesantya sokusasazeka kwe-ultrasonic kubaluleke kakhulu ekulinganisweni kobubanzi be-ultrasonic, indawo, isantya sokuhamba kolwelo, i-modulus ye-elastic yezinto kunye nobushushu begesi ekhawulezileyo. Isixhobo sovavanyo esibanzi sokulinganisa isantya sesandi esenziwe yinkampani yethu sisixhobo sovavanyo esisebenza ngeendlela ezininzi. Asinakubona kuphela into yokuphazamiseka kwamaza amiyo kunye ne-resonance, silinganise isantya sokusasazeka kwesandi emoyeni, kodwa sikwabona ukuphazamiseka kwe-double slit kunye ne-single slit diffraction yamaza esandi, silinganise ubude be-wave yesandi emoyeni, siqwalasele ukuphazamiseka phakathi kwamaza okuqala kunye namaza abonakalisiweyo, njl. Ngolu vavanyo, abafundi banokukwazi ukuqonda imigaqo esisiseko kunye neendlela zovavanyo zethiyori yamaza.

Iithegi zeMveliso

Iimvavanyo

1. Yenza kwaye ufumane i-ultrasound

2. Linganisa isantya sesandi emoyeni usebenzisa iindlela zokuphazamiseka kwesigaba kunye nesandi

3. Funda ngokuphazamiseka kwezandi ezibonakalisiweyo kunye nezasekuqaleni, oko kukuthi, iliza lesandi elithi “LLoyd mirror”

4. Jonga kwaye ulinganise ukuphazamiseka kwesandi okuneziqwenga ezimbini kunye nokuphazamiseka kwesandi okuneziqwenga esinye
