Ke hoʻohana pendulum - alapine (frequency) o ka oscillation

Kiko'î o oscillatory keʻano o ka hanaʻana i pono-ʻikeʻia physical manaÿo - ka ikaika hawewe a me ka wā. Penei, ma lalo o kuekueni hoʻomaopopo mau papa'āweʻaweʻa kemika kānāwai ma ka hana hou ana i ke kaʻina hana o ka hoʻololi 'ana i ka hoʻoponopono nui a puni kona kaulana waiwai' ole 'Aʻohe. E mākou kuhi i kēia kānāwai i ka sinusoidal külana. No laila, ina o ka papa F (x) o ke kaʻina ua haawiia mai ia e keʻano F (x) = K * hewa (m), e like me neia ka oscillating hana, a, e hoomanao, mai a lalo, mai, a ia makou i ...

E noonoo i ka pakuhi o ka la hana o kekahi, ma ka rula, i kekahi waiwai ma ka Y (axis) denoted y1, a neʻe loa ma ka X (axis), y2 loaʻa ka mea e hiki mai anaʻoi me ka waiwai o ka y1. Ano, ina no ka X-(axis), mai ka wahi v2, hoopanee wā mawaena like ia T = (y2 - y1), e hele mākou i ka wahi v3 a me ka mea e e like i ka y1 a me ka y2. Ke kinona o ka pakuhi ma waena o kēia mau kumu pono hai hou ma luna o nā mea a pau mahope Hoʻohana i keia T. Pēlā i loaʻa mākou i ka aiao T no ke kaʻina hana i ho'ākāka 'ia ma ka haʻilula F (x) = K * hewa (m), i loaʻa ai ka waiwai mea kupaianaha e hoʻololi i loko o ka manaʻo hoʻopiʻi kū'ē X T alakai i ka loli i loko o ka papa F (x) ma luna o ka holoʻokoʻa huahelu o kona nā loina. No ka mea, loli ma ka X axis i kona palena i ka manawa, i loko o nā hua'ōlelo, ka helu o nā pōʻaiapuni T infinitely he nui, a laila mākou i ka cyclical, oa Au hou, loli o ke kuleana pili i. Kalapona manawa T ua kapaʻia ka wā o ka oscillation , a ua anaia mai ka manawa i loko o kekona. Akā, oi maliuia mai ia ma ka mea akamai, e hana ana i hui pu ia lakou, a ua kapaia ka oscillation alapine, denoted [illegible] a me ka [illegible] computes = 1 / T, he pa alima ka mea, ua kapaia o Hertz (Hz). Alapine (frequency) o 1 Hz - o kekahi oscillation no kekona.

Mākou i hoopuniia e "i kunewa" honua. Fluctuations - ka mea kani, he uila pono i loko o na kaula, kamakawiwo oleʻano papa hana, no ka malamalama, me ka iʻa, ke kuapo o ka Honua ma ka, a me ... mai i helu ia iwaena, i kēia mau kuekueni. A pau o ia i lawaʻike mau palena o ko lākou mau alapine (frequency), e olelo aku nei "i ka laulā o ka oko a." No ka laʻana, ka oscillation alapine (frequency) o audible kani alapine kanaka - mai ka 16 Hz i 20 kHz (1 kHz = 1000 Hz), a me ka laulā o ke kani alapine colloquially moe ma ka laulā 100 - 4000 Hz. A maopopo mea i ole a pau kanaka i lohe i ka pau huahelu o ka mea kani-- he nui loa ia 12-15 kHz earshot. Keʻano hana pili i ka ultrasonic nä kuekueni 100, 200 kHz, a ma luna. Details maomeka i kekahi fluctuate ma ka laulā nui o nä alapine - a kaʻana like Hz a me na umi o kHz. Akā, ka hapanui i ka laulā huahelu o electromagnetic a hawewe - mai kekahi, a mai ai i na tausani he nui o ka miliona o Hz. Ma keia global pae o ka malamalama ale o ka aina, ua uuku loa, akā, i ka mea i ike ia e mākou nā loko o ka hihiʻo. Okoa oscillation alapine (frequency) i loko o ka pae o ka malamalama ale hoʻoholo i ke ano o ka hiki malamalama - mai ka ulaula i poni.

Akā hoʻi i "huinahalike kekahi." Loa pinepine, ka mea mea kupono e hoʻohana i ka iki Hoʻololi 'huahelu. Oia artifice apono 'e Nohie na mea he nui o na nā papakuhikuhi, a hana ia aku i nanaia. A me keia mea ku pono i ka mea i ka sinusoidal oscillation mana paipai i ka manawa kūpono e hana aiaiiuo ma naehana ana o ka pana pua - radians paha degere. Akā, i ka mea ia manawa, i ka i ka ho omaulia ana o ka "Ke nihi aʻela" a eia i 2p, a, i ke alapine (frequency) i loaʻa pū me ka nui makemakika, ka 'aoʻao. A laila, hoʻoholo ka mea, e alakaʻi mai i ka Hoʻololi 'pa alima o ka alapine (frequency) ana, a haawi aku la ia i ka inoa "cyclic oscillation alapine (frequency)." Ke ae pā o keia pa alima mea i kona alapine (frequency) ua nānā 'ia no ka helu ana o oscillations i 2 * π kekona, a laila 6,28 kek.. Cyclic alapine (frequency) he pōpilikia ma ka haʻilula ω = 2 * π *. F. Pili ana i ka cyclic alapine (frequency) ua olelo ia ma kona pa alima o ana - radians no kekona.

Oscillating'ōnaehana i no kekahi mea kiko'î mea i emi iho kona laʻelaʻe. E ko makou poe elemakule maikai pendulum a me kānaka hōʻuluʻulu, ho'ēmi ia i ka moku'āina o kamakawiwo ole kaʻina - tick-tock, tick-tock. E hana i kēia manawa, He nui iho la e pahu aku ai ia, a ... haʻalele wale. He aha e mākouʻike? A pendulum oscillates lōʻihi lawa me kekahi hou noi o ka ikaika, kona oscillation alapine (frequency) 'aʻole e hoʻololi i, a me ka ikaika hawewe emi i nā, no ka mea, o ka kū'ē kaua i loko o ka maoli manaʻo. Oia fluctuations ka wā initializing ma hope o ka pahu aku ai i o ka pendulum neʻeʻana, a me kekahi 'ē kamakawiwoʻole'ōnaehana ua nānā' wale ma na mea kiko'î, kapa iho. Inā mākou e kuhi ana i ka ia manawa noho koa e like me 'Aʻohe, a me ia mea nui na mea - a pau i loko o ko makou mau lima, e like me ka pendulum, ka mea, ua kapaʻia ka makemakika, e oscillate ka wa pau ole, a me ka oscillation wā hiki ke ho omaulia mai o ka ike, a ua lilo mua i Classic, ka haʻilula - C = 2 * π * √ H / g.

Mai ka Ikepili ia mea hiki ke hana nui i hopena: ke alapine (frequency) maoli o oscillation o ka pendulum ua wale nānā 'ana i ka na mea kiko'î o ka'ōnaehana - ka pae lōʻihi, a me ka nui o ka hoʻonui o ka honua o ka umekaumaha.
