Tazama chanzo cha Marudio (fizikia)

[[File:Falenawodzieanim.gif|thumb|220px|Idadi ya mawimbi yanayopita katika dakika ni kipimo cha marudio]]
[[Picha:FrequencyAnimation.gif|thumbnail|<small>Mfano wa taa inayowaka kwa marudio ya a) <math>f = 0,5\,\text{Hz}</math>, b)<math>f = 1\,\text{Hz}</math> na c)  <math>f = 2\,\text{Hz}</math>.. f ni alama ya Hz katika fomula; 1 Hz inamaanisha ya kwamba taa inawaka mara 1 kila sekunde. 0.5 Hz inamaanisha inawaka kila sekunde 2 = mara 0.5 kila sekunde 2; 2 Hz inawaka mara 2 kila sekunde.<br/> T (alama ya ''tempus'', ''time'') ni alama ya wakati katika fomula, inataja kipindi cha marudio yaani ni sekunde ngapi kutoka kuwaka hadi kuwaka.</small>]]

'''Marudio''' ([[ing.]] ''[[:en:frequency|frequency]]'', alama yake ni '''f''') ni kipimo kichachosema ni mara ngapi tukio linatokea tena na tena kila baada ya kipindi fulani. 

Kwa mfano ukikaa kando la bwawa au bahari penye [[mawimbi]] unaweza kuhesabu ni mawimbi mangapi yanayopita kwako katika dakika moja. Namba hii ni marudio ya mawimbi haya.

[[Kipimo cha SI]] kwa marudio ni '''[[Hezi]]''' (alama Hz). 

==Marudio katika mazingira yetu==
Vitu vingi katika dunia hutokea kwa marudio maalumu. Kutambua marudio ya [[mawimbi]] ya [[nuru]], [[sauti]], [[mawimbi ya sumakuumeme]] na kadhalika kumekuwa msingi kwa sehemu kubwa ya teknolojia tunayotumia, kuanzia [[redio]], [[televisheni]] hadi [[simu]] na [[kompyuta]].

Kwa hiyo marudio ni kipimo muhimu sana katika sayansi na teknolojia ya kisasa.

Marudio yanaweza kutajwa kwa matukio yote ambayo yanatokea mara kwa mara kufuatana na mfumo maalumu. 
*Marudio ya badiliko la mchana na usiku ni  <math>\tfrac1{24\;\mathrm h} \ \approx 10^{-5}\;\mathrm{Hz\,.}</math> 
*[[Moyo]] wa binadamu ina mapigo 50-90 kila dakika hii inalingana na marudio ya 0.83–1.5 Hz). 
*katika bendi au okestra wapiganaji wote wanahitaji kupanga ala zao kwa sauti ya  marudio yaleyale, mara nyingi kwa 440 Hz. 
*[[Sikio]] la kibinadamu hutambua sauti zenye marudio baina ya 20 Hz na 20.000 Hz, ilhali kiwango cha juu hupungua kuluingana na kuzidi kwa umri wa msikiliziaji.
* [[Jicho]] la kibinadamu huona nuru kati ya 400 THz na 750 THz ([[hezi|terahezi]]).
* [[Mawimbi ya sumakuumeme]] ''([[ing.]] electromagnetic waves)'' hutumiwa kwa mawasiliano kwa redio au simu bila waya kuanzia 100 kHz na GHz kadhaa.
