Question

По поверхносте воды в озере волна распростроняется со скоростью 8 м/с каковы переод и частота калебаний бакена если длена волны 2 м

Answer 1

T-период
V-скорость
Л-длина волны(лямда)
Т=Л/V=2/8=1/4=0,25
U-частота=1/0,25=4

Answer 2

Calculation of Period and Frequency of Wave

To calculate the period and frequency of a wave, we need to use the formula:

Period (T) = 1 / Frequency (f)

Given that the wave travels with a speed of 8 m/s and the wavelength is 2 m, we can calculate the frequency using the formula:

Speed (v) = Wavelength (λ) × Frequency (f)

Solving for frequency (f):

f = v / λ

Substituting the given values:

f = 8 m/s / 2 m = 4 Hz

Now, we can calculate the period using the formula:

T = 1 / f = 1 / 4 Hz = 0.25 s

Therefore, the period of oscillation of the wave is 0.25 seconds and the frequency is 4 Hz.

Please note that the above calculations are based on the given information and assumptions.
