Frequency term sunne me jitna difficult lag raha hai utna hi ye easy hai. But bina example is term ko understand karna thoda mushkil kaam ban jata hai. Maine is article me examples ke sath-sath is term ko puri koshish ke sath explain kiya hai.
Frequency us process ko kehte hai jisme time ko har ek second ke baad measure kiya jata hai. Itna hi nahi, balki frequency se wave ki rate pata laga sakte hai jaise sound wave, radio wave aur light wave. Yaneki, kisi bhi action ko second wise recycling ko frequency kaha jata hai.
What is Frequency
Kisi bhi action ko ek-ek second ke baad electronically recycling ko frequency kehte hai. Frequency ka SI unit hertz hota hai jiski short form Hz hai. Yane ki, frequency ki madad se speed rate pata laga sakte hai. For example, agar aap din me 3 baar market jate hai to aapki frequency 3 visits per day hai.

Ab question ye hai ki 3 visits per day ke bajaye 3 hertz kyun nahi bata sakte hai? Jaisa ki maine already kaha ki prati 1 second ke baad jab time ya current change hota rehta hai to usko hum frequency kehte hai jiska unit 1 Hz hai na ki 3 visits. For example, agar electrical current, sound, ya phir light 1 second me ek recycle karta hai to uska frequency 1 Hz hota hai aur isi tarah se agar yehi electrical current, sound, ya phir light 60 seconds me 60 baar recycle karta hai ya change hota hai to iska unit 60 Hz hoga.
Frequency SI Units
Frequency me na keval Hz hota hai lekin isme kHz, MHz, GHz, aur THz bhi unit ko represent karta hai. Ye units alag-alag frequency power ko explain/represent karte hai. For example, 100’s seconds ko Hz se denote kiya jata hai aur kHz large units jo 1000’s me hota hai, usko kHz se denote kiya jata hai.
Hz: hertz = 100’s cycles/currents per second (e.g 1 Hz)
kHz: kilohertz = 1000’s cycles/currents per second (e.g 1 kHz)
MHz: megahertz = 1,000,000’s cycles/currents per second (e.g 1 MHz)
GHz: gigahertz = 1,000,000,000’s cycles/currents per second (e.g 1 GHz)
THz: terahertz = 1,000,000,000,000 cycles/currents per second (e.g 1 TZ)
Aap ne pc me dekha hoga ki usme kaun sa processor hai. Jitna powerful processor hota hai utna hi fast hamara computer kaam karta hai. Suppose, agar kisi computer me 6.4GHz processor laga hua hai to woh ek second me 6,400,000,000 cycles karta hai. Isi tarah se agar kisi pc me 6.4TZ processor hoga to woh ek second me 6,400,000,000,000 cycles karta hai.
Kehne ka matlab ye hai ki agar aapko 4000 cycles ka unit likhna hoga to 4000 Hz incorrect hai balki isko 4 kHz se represent karte hai.
