Question

Звуковая волна распространяется в стали со скоростью 5000 м/с. определите частоту этой волны, если ее длина 6,16 м

Answer 1

частота определяется по формуле f=v/лямбда

где v- скорость распространения волны

лямбда - длина волны

получаем f= 5000/6.16=811.7 Гц

Answer 2

Calculation of the Frequency of a Sound Wave in Steel

To determine the frequency of a sound wave in steel, we can use the formula:

v = λ * f

where: - v is the velocity of the sound wave in steel (given as 5000 m/s), - λ is the wavelength of the sound wave (given as 6.16 m), and - f is the frequency of the sound wave (to be determined).

To find the frequency, we rearrange the formula as follows:

f = v / λ

Substituting the given values, we have:

f = 5000 m/s / 6.16 m

Calculating this expression, we find:

f ≈ 811.69 Hz

Therefore, the frequency of the sound wave in steel, with a wavelength of 6.16 m and a velocity of 5000 m/s, is approximately 811.69 Hz.

Please note that the above calculation assumes that the sound wave is traveling through a homogeneous medium, such as a solid steel rod. In reality, the propagation of sound waves can be influenced by various factors, such as temperature, pressure, and the presence of impurities or defects in the material.
