Wavelength vs Frequency
सूत्र
Sound Wavelength with Temperature
The speed of sound in air increases with temperature, which affects the wavelength.
Formulas
v_sound = 331.3 + 0.606 * T (in m/s, T in Celsius)
lambda = v_sound / f
Higher temperatures produce longer wavelengths at the same frequency.
हल किया गया उदाहरण
Concert A (440 Hz) at 20 degrees Celsius.
- 01v = 331.3 + 0.606 * 20 = 343.42 m/s
- 02lambda = 343.42 / 440
- 03lambda = 0.7805 m
अक्सर पूछे जाने वाले प्रश्न
Why does temperature affect the speed of sound?
Higher temperature means faster-moving air molecules, which transmit pressure waves more quickly.
Is this formula accurate at extreme temperatures?
The linear approximation works well from about -20 to 40 degrees Celsius. Beyond that range, more precise models are needed.
Does humidity affect the speed of sound?
Yes, slightly. Humid air is less dense than dry air (water vapor is lighter than N2/O2), so sound travels a bit faster in humid conditions.
