WebEach separate point is also a point in time. The sine wave describes how any of these properties change during a single cycle. If the frequency is 440 cycles per second (440 Hertz) then the time shown above is 1/440 of a second. Only two attributes are needed to describe a sine wave; its frequency and its amplitude. WebThe y coordinate of the outgoing ray’s intersection with the unit circle is the sine of that angle. It ranges from -1 for x = 3 π / 2 to +1 for π / 2. The function has zeroes where the angle is a multiple of π . Sines of angles between π and 2 π are negative.
