The oscillating points are removed from the source of oscillations by

Okay, I'm ready to answer in Russian!

This product is a device that allows you to create vibrations at points located at a certain distance from the source of these vibrations. The oscillating points can be located at a sufficiently large distance from the source, which allows this device to be used for various purposes, for example, in scientific research or for creating musical effects. The design of the device may vary depending on its purpose and manufacturer, but the basic principle of operation remains the same - creating oscillations at points remote from the source.

This product does not have a specific description because the description is incomplete and does not contain enough information to determine the characteristics of the product. It is necessary to clarify what source of oscillations we are talking about, as well as which points are oscillating and at what distance from the source they are located. Without this information it is impossible to give a more detailed description of the product.

This product has nothing to do with the physical task you described. I am a computer program and cannot sell products. However, I can help you solve the physics problem you described.

So, in accordance with the conditions of the problem, we have:

• Distance between the oscillating points and the source of oscillation: 0.5 m and 1.77 m.
• Oscillation phase difference: 3p/4.
• Source oscillation frequency: 100 s^-1.

To solve the problem, we use the formula for wavelength:

λ = 2πv / f,

where λ is the wavelength, v is the speed of wave propagation, f is the oscillation frequency.

To determine the speed of wave propagation, we use the formula:

v = λf.

Since the oscillation phase difference between the points is 3π/4, then they are at a distance of half the wavelength (because the total phase difference between them is 2π). Thus, we can write:

λ / 2 = 1.77 m - 0.5 m = 1.27 m.

From here we find the wavelength:

λ = 2 * 1.27 m = 2.54 m.

Now you can find the speed of wave propagation:

v = λf = 2,54 м * 100 с^-1 = 254 м/с.

Thus, the wavelength is 2.54 m, and the wave propagation speed is 254 m/s.
