INTRODUCTION

All problems should be solved in a individual way, i.e. each student have its own variant, which is specified by instructor.

Appropriate homework must forego to solving a problem. The homework contains self-studying of theory of sections “Oscillations” and “Waves” of the course of physics for telecommunications technician.

· Complex task is consists of four problems: 3.2; 3.3; 3.4; 3.6. Student must implement on one task from each problem. Concrete number of statement on each stage and initial data in thirty variants is specified in Tables of task variants. Number of the variant is determining by the index of surname of student at a group journal.

· Report is implementing on individual exercise book. Writings should be made on one side of double-page spread.

· On the cover there is need to mark title of the work, number of the variant, surname and initials of student, code of group.

· Calculation part it is necessary to dispose in order of numeration of the problems.

· Calculation part of any problem must contain ten points (see examples):

1. Title of theproblem;

2. Completestatement of a task;

3. Short writing of statement;

Transformation to the system of units SI of a numerical data of given quantities.

5. Scheme or explanatory plan;

6. Listof laws and formulaswhich explain the physical phenomena of theme of the problem. All denotations at the formulas need an explanations;

7. Literal solution. From the listed at point 6 formulas it is necessary to make system ofequations and to obtain expression of each desired quantity through given quantities at the literal (symbolic) representation.

8. Checkout of measurement unit of each desired quantity on correspondence to the expected measurement unit. For this purpose each symbol in the formula of a literal solution to substitute with its measurement unit and realize the necessary transformations.

9.Only after correspondence of measurement units to the expected it is possible to find the numerical solution. Calculation should be transacted with three significant digits.

10. Resultof execution of calculated part.

At the end of work it is necessary to enumerate the list of the used literature.

Besides this guide is recommended to use literature from bibliography given at the end of this guide.
