I am trying to determine the size of a molecule..by doing the oil drop experiment where we drop a tiny droplet of oil on water covered with a thin layer of powder...and then make calculations based on the diameter of the circle... the droplet forms in oil.
ohh i thought u meant without using any microphone...
So i place the mic a distance x from two people who themselves are a distance y between them. Then I ask them to both clap at the same time. and record the distance between the peaks shown on the Oscilloscope?
However, I change x or do I...
So what you are saying is; I connect the microphone to the pre amp. That will amplify the sound waves from the 'clap' and then i monitor the output from the scope?
Hmm..i guess i can clap at increasing or decreasing distances from the mic ?
i tried a simple one by connecting two microphones to the oscilloscope keeping a distance x between them and clapping a distance y from both of them.
But none of my claps, or any music that i played registered any wave fluctuation
I have been given the task to measure the speed of sound in air. The materials available are:
2. Signal Generator
4. Digital Oscilloscope
I have looked through google and the simplest exp involves a loudspeaker as well. However I dont have one...
A particle of mass 4kg is being towed at a constant speed up a rough plane inclined at 30 degrees to the horizontal by a force 4g N acting parallel to the slope. At the top of the slope the particle moves onto a rough horizontal slope with the same coefficient of friction...
