Physics Project : Waves

Waves: Amplitude and Frequency

I used a speaker and some beads to show the principles of amplitude and frequency.

Frequency
The higher the frequency, the more cycles a wave would make in a second, which affects the pitch of sound. As seen when the speaker vibrates more, the pitch gets higher. (1Hz,20Hz,100Hz,1500Hz)

Amplitude
Amplitude is seen the the project as how much the beads move about. The higher the amplitude, the more the beads bounced about and the louder the sound was.

Applications
-Music Synthesis
Synthesizers make use of frequency modulation to make music (eg. A440) Using the variety of frequencies, and different wave shapes (eg. Sine, Square, Sawtooth), interesting sounds can be produce which form music.

so what, his explanation waz perfefct

[666pecker666]

Do you still have those PSB 500's?

Great vid :)

[sethvirgil]

very well explained!

You should improve your speech , I sense a lot of mistake in your speech.

Cool!!Can u saute an Egg in a pan with sound Waves?

it would be very cool if u do that and put it on You tube!
