Not sure what you're saying.
I apoligize for my lack of knowlegdge. I'm returning to school to complete my diploma after being out for 15 years. I picked a course that may be a little to advanced for me but I don't want to lose the money I put down for it.

The answer is 417.42 Hz in the book, I just don't know the order of operations to solve this.

Can you explain where I'm going wrong in my order of operations.
Thanks

Please don't make fun of my question, I just want to have a strong understanding of the meaning and it's use
My textbook just pops these symbols out at me without explanation. Maybe it just expects I know this stuff
In the equation Vs = \Delta d / \Delta t

A ship sends a sonar signal to the bottom of the ocean, 4000 m below. The speed of sound in the seawater under the conditions of the problem is 1500 m/s How much time elapses between the transmission of the signal and the reception of its echo?

Thank you for your quick response. You actually helped clear things up for me quite a bit. Where you said.
I took a look at my diagrams and sure enough that's how it goes for example three nodes and three antinodes would refer to a third resonance.
I'm sure quite obvious to you...

The question I'm working on is
First the diagram:http://http://i215.photobucket.com/albums/cc10/Spookie71/image0-12.jpg
There is the matter of the equation I use to solve the equation:
Can you please explain for me?

Actually forget my last question:
I have a question regarding an equation again.
Required is \lambda
l = \frac{(2n - 1)\lambda}{4}
becomes
\lambda\frac{4l}{(2n - 1)}
I understand that you multiply the 4 by both sides and then bring the 4l over as the numerator. Where it...
Anadyne I appreciate your help. to be honest I'm just a little overwhelmed. It's a lot of new concepts all at once. Just a matter of processing them. I guess it would help a little if I knew where we are going and where I will apply this later in Physics. It's a lot to remember how sound...
So those pictures that i posted for you are based on using different frequencies, that makes more sense to me. the applet makes a lot more sense. The page didn't really say it was using different frequencies, just that there was a 2nd and 3rd Resonant.
Still confused but the overall picture...
