## Part II - Simple Wave Motion in 1D

Simple wave motion in one dimension means that the particle is constrained to move along a line,
instead of moving in other space.

#### Basic Parameters

A fundamental equation consists on four parameters - A, c, , .

**A** - amplitude of the wave

**c** - the velocity of the wave

- the radian frequency of the wave

- the wavelength

#### Other parameters

Some other parameters are often used also.

T - period of the wave

*f* - frequency

#### Wave equation

The general wave equation is y = Acos(2/(x-ct)).

It can also be written in terms of : y = Acos((2/)x - t).
