1. The experiment is one of the academic activities undertaken by them for the purposes of scientific knowledge, the discovery of regularities and changes to existing practices. The experiment is a unique combination of organizational, practical and theoretical activity of the researcher, which gives the possibility to isolate the phenomenon being studied from the influence of adverse, non-existent factors, to study it in its "pure form". The difference from experiment of excellence is the presence of special purpose scientific study. The researcher is interested not only in the results of the experiment, how many General and specific regularities of the learning process. The main research methods are the methods of accumulation of knowledge and facts. To obtain the facts there are a variety of methods.

2. Under the wave velocity see velocity of propagation of disturbance. For example, a blow on the end of the steel rod in it causes local compression, which then spreads along the rod at a speed of about 5 km/s. the wave Velocity is determined by the properties of the medium in which the wave propagates. At the transition of the wave from one medium to another its speed changes.

Wavelength is the distance the wave propagates for a time equal to the period of oscillations in it. Since the wave velocity is a constant value (for a given environment), we traveled by a wave is the distance equal to the product of speed at the time of its distribution. Thus, to find the wavelength, the wave speed multiplied by the period of oscillation in it:

3. State of matter - the state of one and the same substance in a certain range of temperatures and pressures. Traditionally, there are three aggregate States: solid, liquid and gas. To aggregate the States also made to rank the plasma, in which pass the gases with increasing temperature and a fixed pressure.

4. Electromagnetic induction is the phenomenon of electric current in a closed circuit when the magnetic flux passing through it. Electromagnetic induction was discovered by Michael Faraday on August 29, 1831. According to the law of electromagnetic induction Faraday (in C): , where is the electromotive force acting along a randomly selected path,
- the magnetic flux through the surface bounded by this contour.
