Question

Звуковая волна проходит расстояние 990 м за 3 с. определить длину волны если частота колебаний равна 660 Гц.

Answer 1

V= s/ t=990/ 3=330 м/с
L= V /v= 330/ 660= 1/2=0.5 м

Answer 2

Calculation of Wavelength

To determine the wavelength of a sound wave, we can use the formula:

Wavelength = Speed / Frequency

Given that the sound wave travels a distance of 990 m in 3 s and the frequency of oscillation is 660 Hz, we can calculate the wavelength.

Calculation:

Speed of sound waves is not provided in the question, so we will use the average speed of sound in air, which is approximately 343 m/s.

Speed = 343 m/s

Frequency = 660 Hz

Using the formula:

Wavelength = Speed / Frequency

Wavelength = 343 m/s / 660 Hz

Calculating the wavelength:

Wavelength ≈ 0.520 m

Therefore, the wavelength of the sound wave is approximately 0.520 meters.
