Faib qhov nrawm los ntawm wavelength.
Faib qhov nrawm ntawm nthwv dej, V, los ntawm wavelength hloov mus rau hauv meters, λ, thiaj li nrhiav tau tus zaus , f.
Ua kom pom qhov no, koj yuav pom qhov zaus ntawm lub wavelength li cas?
Rau xam wavelength , siv cov qauv wavelength = ceev muab faib los ntawm zaus . Cia li ntsaws rau hauv nthwv dej ceev thiab zaus daws rau cov wavelength . Nco ntsoov siv cov units kom raug thaum koj siv lub qauv thiab sau koj cov lus teb.
Tsis tas li ntawd, qhov wavelength ntawm 1 Hz yog dab tsi?
| Ntau zaus | Lub wavelength |
|---|---|
| 1 MHz = 1,000,000 Hz = 106 Hz | 300 m |
| 10 MHz = 10, 000, 000 Hz = 107 Hz | 30 m |
| 100 MHz = 100, 000, 000 Hz = 108 Hz | 3 m ua |
| 1000 MHz = 1000, 000, 000 Hz = 109 Hz | 0,3m ua |
Kuj nug, koj nrhiav tau qhov zaus li cas?
A zaus yog tus naj npawb ntawm lub sij hawm cov ntaub ntawv muaj nqis tshwm sim. Piv txwv li, yog tias kaum tus tub ntxhais kawm tau qhab nia 80 hauv kev txheeb cais, ces tus qhab nia ntawm 80 muaj a zaus ntawm 10. Ntau zaus feem ntau sawv cev los ntawm tsab ntawv f. A zaus daim ntawv qhia yog tsim los ntawm kev npaj cov ntaub ntawv muaj nuj nqis nyob rau hauv ascending order of magnitude nrog rau lawv zaus.
Dab tsi yog unit rau wavelength?
Cov units ntawm wavelength yog nyob rau hauv ' meter ', nws qhov ntau los yog feem ntawm ib 'meter'. Raws li qhov zaus nce, lub wavelength txo qis, yog tias qhov nrawm nrawm nrawm. Piv txwv li, nthwv dej ntawm cov frequencies siab heev muaj luv heev wavelengths.

Yuav ua li cas koj nrhiav tau daim ntawv tivthaiv ntawm ib vector muab qhov magnitude thiab lub kaum sab xis?
VIDEO Khaws qhov no hauv kev xav, puas yog 0 ib chav vector? A unit vector yog a vector uas muaj qhov loj ntawm 1. Cov ntawv sau sawv cev rau tus qauv, lossis qhov loj, ntawm vector v. Basic unit vectors yog i = (1, 0 ) thiab j = ( 0 , 1) uas yog ntev 1 thiab muaj cov lus qhia raws qhov zoo x-axis thiab y-axis feem.
Yuav ua li cas koj nrhiav tau qhov sib npaug ntawm ib kab uas muab ib tug point thiab ib tug parallel kab?
Qhov sib npaug ntawm kab hauv daim ntawv nqes hav-intercept yog y = 2x + 5. Qhov nqes hav ntawm parallelline yog tib yam: m = 2. Yog li, qhov sib npaug ntawm kab sib npaug yog y = 2x + a. Txhawm rau nrhiav ib qho, peb siv qhov tseeb tias kab yuav tsum dhau los ntawm qhov muab: 5 = (2) ⋅ (− 3) + a
Yuav ua li cas koj nrhiav tau tus txheeb ze zaus nyob rau hauv ib txwm faib?
Faib cov suav (qhov zaus) los ntawm tag nrho tus lej. Piv txwv li, 1/40 = . 025 3/40 = . 075 ib
Yuav ua li cas koj nrhiav tau yoj ceev muab zaus thiab wavelength?
Ceev = Wavelength x Wave Frequency. Hauv qhov sib npaug no, wavelength yog ntsuas hauv meters thiab zaus ntsuas hauv hertz (Hz), lossis tus naj npawb ntawm nthwv dej ib ob. Yog li ntawd, yoj ceev yog muab nyob rau hauv meters ib ob, uas yog lub SI unit rau ceev
Yuav ua li cas koj nrhiav tau qhov sib npaug ntawm ib tug hyperbola muab Asymptotes thiab foci?
Siv qhov laj thawj saum toj no, qhov sib npaug ntawm cov asymptotes yog y = ±ab(x−h) + k y = ± a b (x − h) + k. Zoo li hyperbolas nyob nruab nrab ntawm lub hauv paus chiv keeb, hyperbolas nyob nruab nrab ntawm qhov taw tes (h, k) muaj vertices, co-vertices, thiab foci uas cuam tshuam los ntawm kab zauv c2 = a2 + b2 c 2 = a 2 + b 2
