Document Summary

When two motions are together they are at their in phase. If one motion is too quick the pendulum stays almost still, and any motion it has all be the opposite of the first, or its out of phase. Wether or not we can price a light depends on the amplitude of the wave. A sine wave is the simplest wave. There are also periodic and non repeating waves. The period of a periodic wave is the tie in between repetitions that we find if we stand at one place. Inverse of period is frequency and this how many many oscillations occur in one second at a fixed point in space. Wavelength is categorized by space behavior whereas frequency is categorized by time behavior. Speed of a wave = frequency x wavelength to u = v x . Em waves in a vacuum = 300,000,000 m/sec v x = c.
