Glass rattles in the window when a speaker is turned on in the house opposite, located at a distance of 33 meters

Glass rattles in the window when a speaker is turned on in the house opposite, located at a distance of 33 meters, and a loud sound is heard from it, the wavelength of which is 10 cm. What is the natural frequency of oscillations of the window glass if the speed of the sound wave is 330 m / s?

To find the value of the natural vibration frequency of the presented window glass, we apply the formula: ν = V / λ.

Variables: V is the speed of the sound wave from the speaker (V = 330 m / s); λ – wavelength (λ = 10 cm = 0.1 m).

Calculation: ν = V / λ = 330 / 0.1 = 3.3 * 10 ^ 3 Hz.

Answer: The natural vibration frequency of the presented window glass is 3.3 kHz.
