Frequency vs Wave Speed
सूत्र
Frequency
Frequency is the number of complete wave cycles passing a point per second.
Formula
f = v / lambda
The reciprocal of frequency is the period: T = 1 / f = lambda / v.
हल किया गया उदाहरण
Sound traveling at 343 m/s with a wavelength of 0.78 m.
- 01f = v / lambda
- 02f = 343 / 0.78
- 03f = 439.7 Hz
- 04T = 1 / f = 0.002274 s
अक्सर पूछे जाने वाले प्रश्न
What is the audible frequency range for humans?
Roughly 20 Hz to 20,000 Hz. Frequencies below 20 Hz are infrasound; above 20 kHz are ultrasound.
How does frequency relate to pitch?
Higher frequency corresponds to higher perceived pitch. Doubling the frequency raises the pitch by one octave.
Can frequency change as a wave moves between media?
No. Frequency stays constant when a wave passes from one medium to another; it is the wavelength and speed that change.
