Mafungu: iyo nguva yakawanda yevheji kuburikidza nerefu uye mamwe mazano

Iyo yakareba inokosha inhengo yemuviri inokosha inodiwa yekugadzirisa matambudziko akawanda e acoustics nemavhidhiyo emagetsi. Inogona kuverengwa nenzira dzinoverengeka, zvichienderana nemiganhu iyo inogadzirirwa. Ndizvo zvakanakisisa kuita izvi, kuziva nguva kana nguva uye nekukurumidza kwekupararira.

Formulas

Chirevo chekutanga chinopindura mubvunzo wekuwana mawandei kuburikidza nehuwandu hunoitwa pasi apa:

L = v / u

Pano ndiyo kuwedzera kwemamita, v ndiyo kuparadzirwa kwayo mu m / s, uye u ndiyo nguva inowanikwa mumhepo.

Sezvo nguva yakawanda yakabatana nenguva iyo kuburikidza nehukama hwakasvibiswa, izwi rekare rinogona kunyorwa zvakasiyana:

L = vT

T ndiyo nguva yekuscillation mumasekondi.

Zvinokwanisika kuratidza iyi parameter kuburikidza ne cyclic frequency uye phase velocity:

L = 2 pi * v / w

Mutsara iyi, w ndiyo inofanirwa kuenderera mberi inonzi radians pamusi wechipiri.

Kuwedzerwa kwemafunguro kuburikidza nehurefu, sezvinogona kuonekwa kubva pamashoko ekutanga, zvinotevera:

U = v / l

Funga nezvemagetsi emagetsi anopararira mune chimwe chinhu ne refractive index n. Ipapo huwandu hwemhepo inotenderera kuburikidza nehurefu hunoratidzwa nehuwandu hunotevera:

U = c / (l * n)

Kana iyo inopararira muvharo, ipapo n = 1, uye mazwi anotora fomu inotevera:

U = c / l

Mukushambadzira kwekupedzisira, kuwanda kwemafuro kuburikidza nehurefu kunotsanangurwa kushandiswa kushandiswa kwechigarire c = kuwedzera kwechiedza muvharo, c = 300,000 km / s.

Waves de de Broglie

Nokuda kwemafungu aya, maitiro acho achava nenzira yakasiyana zvakasiyana. Vanoona kuti zvinogona kuwanda uye zvinoshandiswa pakuwanda kwemagetsi kuti vawane zviyero zvechikamu chinenge chichifungidzirwa. Kureba uye nguva dzinotsanangurwa zvinotevera:

L = h / p

U = E / h

H ndiyo nguva yekugadzirisa, p ndiyo inokura, uye E ndiyo simba.

Kushanda

Izvo zvataurwa pamusoro apa zvinogona kushandiswa kuwana mitsara yemagetsi nemagetsi eimwe chimiro, muvharo, mhepo kana imwe midzi. Kuti uone kuti kuwedzerwa kwemafunguro kunoratidzirwa sei maererano nehurefu kana zvakasiyana-siyana, munhu anofanira kuziva kukurumidza kwekupararira kwayo uye zvinhu zvepakati. I-electromagnetic inogona kunge ichienda mumhepo kana mumhepo, nemhaka yepamusoro magetsi uye magnetic permeability, sezvo kubhururuka kwayo kunopesana zvichienderana nemidzi yechigadzirwa chezvidimbu.

Neine mhepo yakajeka pachava nemamwe mamiriro ezvinhu. Inomutinhiro mutsva mune zvakasimba uye zvinodhaka zvakakura kudarika mumhepo. Nhanho yakakwirira inenge ine iron uye lithium (inenge 6000 m / s), girazi - 4800 (m / c), ndarama, sirivha, platinum. Nhanyo yemutsindo yakasimba uye yakasvibirira inogadziriswa nezvakaoma zvakaoma kuzvidzora, zvichifunga kuwanda kwepakati uye vechidiki.
