Greetings,

I have a write-up and power point for using the aluminum rod to find the
speed of sound in it. I sent them as an attachment to Aaron Titus.

Go to www.cvcaroyals.org/~rheckathorn, check on Regular Physics, then
on Sound to get the files.

Subject: speed of sound in a solid

I'd like to set up an oscilloscope and microphone to measure the speed
of sound in a solid (like aluminum). Does anyone have a detailed
description on how to set it up? I'd like to use it as a demo on Wed
but don't have much time between now and then to play with it. So a
detailed description is probably necessary for me right now. I figure
that it requires triggering the scope on the initial "clang" of the
pipe and then measuring the time between this wave and the one picked
up by the mic. However, I haven't worked with external triggering
before.

Thanks so much,

AT

I think the charged ions in the flame are deflected by the Lorentz
force. Does reversing the magnet reverse the direction of the deflection?

Did you ever place a candle between two charged plates and then charge
the plates (with a Whimshurst or VdG)? Try it - very neat.

Special bonus discount for those who can answer the following question:

How long would one have to wait to determine whether the frictionless, rigid
plane was level by watching the motion of a particle on it?

long enough to see if it accelerates?
