Question

. Определите частоту звука, издаваемого струной, если длина волны 0,2 м, а скорость распространения 300 м/с.

Answer 1

U=λv, отсюда 
v=U/λ=300/0,2=1500 Гц

Answer 2

Calculating the frequency of a vibrating string

The question asks us to calculate the frequency of the sound produced by a vibrating string, given its wavelength and the speed of sound.

The formula that relates wavelength (λ), frequency (f), and speed of sound (v) for a vibrating string is:

f = v/λ

Plugging in the values given: - Wavelength (λ) = 0.2 m - Speed of sound (v) = 300 m/s

**f = v/λ f = 300 m/s / 0.2 m f = 1500 Hz**

So the frequency of the sound produced by the string is 1500 Hz.
