Question

Два когерентных источника звука колеблются в одинаковых фазах. В точке, отстоящей от первого источника на 2 м, а от второго - на 2,5 м, звук не слышен. Скорость звука равна 340 м/с.определить частоту колебаний источников )

Answer 1

Волны ослабляют друг друга если на разности хода укладывается пол волны
Значит у тебя пол волны то есть лямбда/2 = 2,5-2= 0,5 метров
Значит длина звуковой волны 1 м
Найдем частоту источник из формулы V= лямбда * ню
ню = V/ лямбда= 340 Гц

Answer 2

Calculation of the Frequency of the Sound Sources

To determine the frequency of the sound sources, we can use the information provided in the question. We know that two coherent sound sources are oscillating in the same phase. At a point that is 2 meters away from the first source and 2.5 meters away from the second source, the sound is not audible. The speed of sound is given as 340 m/s.

Let's calculate the frequency of the sound sources using the formula:

Frequency = Speed of Sound / Wavelength

To find the wavelength, we can use the formula:

Wavelength = Distance between the two sources - Distance from the first source

Given that the distance between the two sources is 2.5 meters and the distance from the first source is 2 meters, we can calculate the wavelength:

Wavelength = 2.5 m - 2 m = 0.5 m

Now, we can calculate the frequency using the speed of sound and the wavelength:

Frequency = 340 m/s / 0.5 m = 680 Hz

Therefore, the frequency of the oscillations of the sound sources is 680 Hz.

Please note that the sources provided did not directly answer the question. However, the calculation is based on the principles of wave interference and the properties of sound waves.
