Question

рыболов заметил, что за 20 секунд поплавок совершает 40 колебаний, а расстояние между соседними горбами волны составляет 1,5 метра. Какова скорость распространения волны?

Answer 1

Calculation of Wave Speed

To calculate the wave speed, we can use the formula:

Wave Speed = Frequency × Wavelength

In this case, we are given the frequency of the wave, which is the number of oscillations or vibrations per unit time. The frequency is given as 40 oscillations in 20 seconds.

We are also given the distance between neighboring wave crests, which is the wavelength. The wavelength is given as 1.5 meters.

Using the formula, we can calculate the wave speed as follows:

Wave Speed = 40 oscillations / 20 seconds × 1.5 meters

Calculating this expression, we find that the wave speed is 3 meters per second.

Please note that the search results did not provide any relevant information for this specific question. However, the calculation of wave speed is a basic concept in physics and can be derived using the formula mentioned above.
