Mafungu anotenderera uye akareba - matambudziko nemhinduro

Mafungu anotenderera uye akareba - matambudziko nemhinduro

1. A wave iri kufamba newaya yakareba mamita matatu kwemasekondi 0.3. Nguva yemafungu chii?

Zvinozivikanwa:

Nguva yepakati (t) = masekondi gumi nemashanu

Zvaidiwa: Nguva (T)

Solution:

1 wavelength = 1 goko + 1 chirongo

Nguva = 2 x 0.1 masekondi = 0.2 masekondi

2. Kumhanya kwemafungu zvichienderana nemufananidzo uri pazasi ndekwekuti…

Zvinozivikanwa:

Wavelength imwe ine goko rimwe chete uye gomba rimwe chete. Zvichienderana nemufananidzo uri pamusoro, wavelength imwe chete = mamita maviri x 4 = mamita masere.

Nguva yemafungu (T) = 0.5 x 4 = 2 masekondi

Zvaidiwa: Kumhanya kwemafungu (v)

Solution:

Kumhanya kwemafungu:

v = s / t = λ / T = mamita 8 / masekonzi maviri = mamita 4/sekondi

3. Daro riri pakati pemapoinzi A neB i30 cm. Chii chinonzi kumhanya kwemafungu zvichienderana nemufananidzo uri pazasi?

Zvinozivikanwa:

Kubva paA kusvika paB, pane ¾ wavelength. Kana daro riri pakati paA naB riri 30 cm, saka daro re ¼ wavelength i30 cm / 3 = 10 cm. Saka, daro rimwe chete = 4 x 10 cm = 40 cm.

Zvichienderana nemufananidzo uri pamusoro, nguva yemafungu imasekondi mana.

Zvaidiwa: The kumhanya kwemafungu (v)

Solution:

v = d / t = λ / t

v = kumhanya kwemafungu, d = daro, λ = kureba kwemafungu, t = nguva yekufamba

Kumhanya kwemafungu:

v = λ / t = 40 cm / 4 masekondi = 10 cm / 1 sekondi = 10 cm/sekondi

4. Kana daro reA neB = 250 cm, saka kumhanya kwemafungu kuri…

Zvinozivikanwa:

Kureba kweA neB = 5/4 wavelength = 250 cm.

1/4 kureba kwemasendimita = 250 cm / 5 = 50 cm

1 wavelength = 4/4 wavelength = 4 x 50 cm = 200 cm

Nguva (T) = masekondi maviri

Zvaidiwa: Kumhanya kwemafungu

Solution:

Fomura yekumhanya kwemafungu:

v = d / t = λ / t

v = kumhanya kwemafungu, d = daro λ = kureba kwemafungu, t = nguva yekufamba

Kumhanya kwemafungu:

v = 200 cm / 2 masekondi = 100 cm/sekondi

5. Kukura kwemafungu kunoratidzwa ne….

Solution:

Hurefu hwemafungu ndiBB' naDD”.

1. Chii chinosiyanisa mafungu anochinjika kubva kumafungu enguva refu maererano nekufamba kwezvikamu?
   • mhinduro: Mumafungu anochinjika, zvidimbu zvepakati zvinofamba zvakatarisa divi rekupararira kwemafungu. Mumafungu anochinjika, zvidimbu zvinofamba zvakatarisa divi rekupararira kwemafungu.
2. Inopa muenzaniso wakajairika wefungu rakachinjika uye fungu refu.
   • mhinduro: Muenzaniso wakajairika wefungu rakachinjika ifungu riri patambo kana mafungu emvura. Muenzaniso wakajairika wefungu rakachinjika ifungu reruzha riri mumhepo.
3. Zvinhu zvakasimba zvinogona kutsigira mafungu anochinjika uye mafungu enguva refu here?
   • mhinduro: Ehe, zvinhu zvakasimba zvinogona kutsigira mafungu anochinjika uye mafungu enguva refu. Zvisinei, mafungu (magasi nezvinwiwa) anowanzo tsigira mafungu enguva refu chete.
4. Kudzvanywa uye kushomanana kwenzvimbo zvinobatana sei nemafungu enguva refu?
   • mhinduro: Mumafungu enguva refu, kudzvanywa kunoreva nzvimbo ine zvidimbu zvepakati zviri pedyo, uye rarefaction inoreva nzvimbo ine zvidimbu zviri kure zvakanyanya. Nzvimbo idzi dzinoenderana nemakona nematafura ari mumafungu anotenderera.
5. Sei tichigona kunzwa ruzha (mafungu enguva refu) tichitenderedza makona asi tisingaoni chiedza (chinoita semafungu anochinjika) nenzira imwecheteyo?
   • mhinduro: Ruzha runogona kuparadzanisa, kana kupararira, pedyo nezvipingamupinyi zvakanyanya kupfuura chiedza nekuda kwehurefu hwaro hwemafungu kana tichienzanisa nechiedza chinoonekwa. Kunyange zvazvo ruzha nechiedza zvichiratidza kuparadzaniswa, mafungu mapfupi echiedza chinoonekwa zvinoreva kuti mhedzisiro yaro yekupararira hainyanyi kuoneka muzviitiko zvezuva nezuva.
6. Kumhanya kwemafungu anochinjika uye akareba munzvimbo imwe chete kunoenzaniswa sei?
   • mhinduro: Kumhanya kwemafungu anochinjika nemarefu munzvimbo imwe chete kunogona kusiyana. Semuenzaniso, mune zvakasimba, kumhanya kwerefuti (P-wave) kunowanzo mhanya kupfuura kwerefuti (S-wave).
7. Chinhu chepakati chinogona kuratidza kufamba kwemafungu panguva imwe chete here?
   • mhinduro: Ehe, mamwe matambudziko anogona kukonzera mafungu anochinjika uye mafungu enguva refu panguva imwe chete. Semuenzaniso, kudengenyeka kwenyika kunogadzira mafungu eP (longitudinal) uye mafungu eS (transverse) anofamba nepasi.
8. Rudzii rwemafungu runogona kukonzera mhedzisiro inoparadzanisa kana apararira?
   • mhinduro: Mafungu anotenderera anogona kupokana. Kupokana kunosanganisira kuganhurira kutenderera kune imwe nzvimbo. Mafungu erefu, nekuda kwekufamba kwawo kumashure nekunze, haagone kupokana nenzira iyi.
9. Mafungu emagetsi akaita semafungu echiedza kana eredhiyo akaita sei?
   • mhinduro: Mafungu emagetsi mafungu anochinjika. Simba rawo remagetsi nemagineti rinotenderera zvakananga kunzira yekupararira kwemafungu.
10. Sei maS-wave (rudzi rwemafungu anochinjika) asingaonekwe achifamba nepakati penyika panguva yekudengenyeka kwenyika?

• mhinduro: Mafungu eS haafambi nepakati penyika nekuti anofungidzirwa kuti imvura. Mafungu anotenderera anoda chinhu chinogona kutsigira kumanikidzwa kwemvura, izvo zvinhu zvakasimba zvinogona kutsigira, asi mvura (zvinwiwa nemagasi) hazvigone.
