Question

Прочитайте и письменно переведите следующий текст. Составьте 5 вопросов к тексту. WAVES AND WAVE – MOTION We see water waves almost every day, we make use of light waves to see the water waves; we hear sounds by means of sound waves. Wave – motion is everywhere. Water waves, light waves, sound waves, any kind of waves, have one thing in common. They transmit energy through a medium by means of vibrations of the particles, but the medium as a whole is not changed or displaced. The number of complete vibrations per second is called the frequency of the wave-motion. The distance between the top of one wave and the top of the next (or between the bottom of one wave and the bottom of the next) is called the wave-length. To find the speed of the wave-motion we multiply the frequency by the wave-length. This important equation is true for any kind of waves.

Answer 1

ВОЛНЫ И ВОЛНА - ДВИЖЕНИЕ

Мы видим волны на воде почти каждый день, мы используем световые волны, чтобы увидеть волны на воде; мы слышим звуки с помощью звуковых волн. Волна - движение везде. Водные волны, световые волны, звуковые волны, любые волны имеют одну общую черту. Они передают энергию через среду посредством колебаний частиц, но среда в целом не изменяется и не смещается. Число полных колебаний в секунду называется частотой волнового движения. Расстояние между вершиной одной волны и вершиной следующей (или между основанием одной волны и основанием следующей) называется длиной волны. Чтобы найти скорость волнового движения, мы умножаем частоту на длину волны. Это важное уравнение верно для любых волн.

Answer 2

Waves and wave motion are phenomena that are observed in various forms in our daily lives. We can see water waves almost every day, and we use light waves to see these water waves. Similarly, we hear sounds by means of sound waves. Wave motion is present everywhere, whether it is water waves, light waves, sound waves, or any other kind of waves. One common characteristic of waves is that they transmit energy through a medium by means of vibrations of the particles. However, the medium as a whole is not changed or displaced.

The frequency of wave motion refers to the number of complete vibrations per second. It determines how many cycles of a wave occur within a certain time frame. On the other hand, the wavelength refers to the distance between the top of one wave and the top of the next (or between the bottom of one wave and the bottom of the next). It represents the length of one complete cycle of the wave.

To calculate the speed of wave motion, we multiply the frequency by the wavelength. This equation holds true for any kind of waves, including water waves, light waves, and sound waves. Understanding the speed of wave motion helps us study and analyze wave behavior and phenomena in different contexts.

Questions: 1. What are some examples of waves that we encounter in our daily lives? 2. How do we perceive water waves using light waves? 3. How do we hear sounds through sound waves? 4. What is the common characteristic of all types of waves? 5. How can we calculate the speed of wave motion?
