کیا ہے Frequency Calculator?

▾

A frequency calculator computes the frequency of a wave from its period, or vice versa. Also converts between frequency and wavelength using the wave speed equation.

فارمولا

▾

f(x)Frequency = number of occurrences / total time period; Period (T) = 1 / frequency; Hz = cycles per second

کیسے Frequency Calculator

▾

1f = 1/T (frequency = 1 / period)
2T = 1/f (period = 1 / frequency)
3For electromagnetic waves: λ = c/f where c = speed of light
4For sound: λ = v_sound/f where v_sound ≈ 343 m/s at 20°C

حل شدہ مثالیں

مثال 1

دیا گیا:Period T = 0.005 seconds

نتیجہ:f = 1/0.005 = 200 Hz

مثال 2

دیا گیا:Radio frequency 100 MHz

نتیجہ:λ = 3×10⁸/10⁸ = 3 metres

اکثر پوچھے جانے والے سوالات

▾

What's a hertz?

1 Hz = 1 cycle per second. AC power is 50 Hz (UK) or 60 Hz (USA).

How do frequency and wavelength relate?

Wavelength (λ) = speed (c) / frequency (f). Higher frequency = shorter wavelength.

Can I measure frequency at home?

Yes, using oscilloscopes, frequency meters, or smartphone apps for sound. Requires appropriate equipment for precise measurement.
