Question

Скорость звука в воздухе 340м/с.длина звуковой волны в воздухе для самого низкого мужского голоса достигает 4,3м.определите частоту колебаний этого голоса

Answer 1

l-это лямбда длина волны
u-скорость волны
V-частота

V=U\L=340\4,3=80 гц


 

Answer 2

Calculation of Frequency

To determine the frequency of the lowest male voice with a sound wave length of 4.3 meters, we can use the formula:

Frequency (f) = Speed of Sound (v) / Wavelength (λ)

Given that the speed of sound in air is 340 m/s and the wavelength is 4.3 meters, we can substitute these values into the formula to calculate the frequency:

f = 340 m/s / 4.3 m

Calculating this, we find:

f ≈ 79.07 Hz

Therefore, the frequency of the lowest male voice with a sound wave length of 4.3 meters is approximately 79.07 Hz.
