LMEC-15 Interference, Diffraction and Velocity ana ana o ka hawewe kani

ʻO ka wehewehe pōkole:

Nānā: ʻaʻole i hoʻokomo ʻia ka oscilloscope

Ma nā hana pono, ʻo ke ana o ka ultrasonic propagation velocity he mea nui ia i ke ana o ka ultrasonic ranging, positioning, liquid flow velocity, material elastic modulus and instantaneous gas wela. ʻO ka mea kani hoʻokolohua holoʻokoʻa i hana ʻia e kā mākou hui he mea hoʻokolohua multifunctional. ʻAʻole hiki iā ia ke nānā wale i ke ʻano o ka hawewe kū a me ka hoʻopiʻi ʻana, e ana i ka wikiwiki o ka hoʻolaha ʻana o ke kani i ka lewa, akā e nānā pū i ka ʻāpana ʻāpana pālua a me ka ʻokoʻa o ka hawewe kani hoʻokahi, e ana i ka lōʻihi o ka hawewe kani i ka lewa, e nānā i ka interference ma waena o ka nalu mua a me ka nalu i ʻike ʻia, etc.

E hoʻouna i ka leka uila iā mākou

Nā hoʻokolohua

1. Hana a loaʻa i ka ultrasound

2. E ana i ka wikiwiki o ka leo me ka hoʻohana ʻana i nā ʻano hana hoʻopilikia i ka pae a me ka resonance

3. E aʻo i ka hoʻopili ʻana o ka nalu kani mua, ʻo ia hoʻi ka hawewe kani "LLoyd mirror" hoʻokolohua.

4. E nānā a ana i ka hoʻokolo ʻana o nā ʻāpana ʻelua a me ka ʻokoʻa hoʻokahi o ka hawewe kani
