Question

Две точки находятся на прямой, вдоль которой распространяется волна со скоростью 10 м/с. Период колебаний равен 0,2 с, расстояние между точками 1 м. Найти разность фаз колебаний в этих точках.

Answer 1

X=1 м  dф=w*x/V
w=2*pi/T
dф=2*pi*x/T*V=2*pi*1/0,2*10=pi

Answer 2

Calculation of Phase Difference

To find the phase difference between two points on a wave, we need to consider the period of oscillation, the velocity of the wave, and the distance between the two points.

Given: - Wave velocity (v) = 10 m/s - Period of oscillation (T) = 0.2 s - Distance between the points (d) = 1 m

The formula to calculate the phase difference (Δφ) is:

Δφ = 2π * (d / λ)

where λ is the wavelength of the wave.

To find the wavelength, we can use the formula:

λ = v * T

Substituting the given values:

λ = 10 m/s * 0.2 s = 2 m

Now we can calculate the phase difference:

Δφ = 2π * (1 m / 2 m) = π radians

Therefore, the phase difference between the two points is π radians.
