What is the wavelength of a 512 Hz sound wave in 20 degree C air?
What is the frequency of a light wave that has a wavelength of 0.0025m?
To find the wavelength of a sound wave, you can use the formula:
wavelength = speed of sound / frequency
Where:
- speed of sound in air at 20 °C is approximately 343 meters per second (m/s)
- frequency is 512 Hz
Substituting these values into the formula, we can calculate the wavelength:
wavelength = 343 m/s / 512 Hz ≈ 0.6719 meters (m)
Therefore, the wavelength of a 512 Hz sound wave in 20 °C air is approximately 0.6719 meters.
