a baton
orchestra's conductor wave to keep time
He gives the tempo, but he also controls his musicians, tells them to be more expressive, louder, go faster etc.
To wave a little stick and hope the orchestra actually pays attention to what s/he is doing. To teach them phrasing, to help keep them together. To see what the orchestra overlooks.
That stick they wave around is called a baton.
Draw a sine wave, except that when it wants to go negative, keep it at zero instead.
because the sound waves combine to make a bigger louder wave
v = w*f. If w (wave length) is increased f (frequency) must go down to keep v (velocity) constant.
The speed of a wave is how far the wave travels in one unit of time.
A sound wave decreases over time because of natural dissipation, which refers to the energy lost as the sound propagates through a medium like air. As the wave travels, some of its energy is converted into other forms (like heat) and is no longer available to keep the wave going, resulting in a decrease in amplitude and intensity over distance.
The time it takes for a wave to pass a given point is known as the period of the wave. It is the time it takes for one complete cycle of the wave to pass the point. The period of a wave is inversely proportional to its frequency.
when is it the best time to visit wave rock
The distance that a wave travels in a certain amount of time is a wavelength. Wrong,it's speed.(:
