Hi all, I'm a senior in high school right now, and and headed for Kansas State University, fall 08. I'm genuinely curious about how the universe behaves, and learning to predict its patterns, as well learning why things work. This lead me to want to double major in physics and mathematics...

Hi, I want to get a bachelor's in physics and math, with a master's in engineering... that's the plan, but what I'm really into is high tech audio hardware; monitors, mixers, etc... I'd really like to design this type of technology---does anyone know how I would go about getting to this...

oh, cool, yeah i remember seeing that equation somewhere before... right so: v= (150/(0.65Kg/28m))^.5 take that number, given the length of the cord I can solve for time

Homework Statement a cord of mass 0.65 Kg is stretched between two supports 28 m apart, The tension of the cord is 150 N, how long will it take a pulse to go from one end to the other? Homework Equations ok, so I really know is: speed of wave=frequency*wavelength... The Attempt at a...

so, that's all been very helpful... but how does tension relate to the wave equation: V = wavelength * frequency)

oh, OK thanks a bunch!

oh yeah, I found something in my friend's college textbook, saying that: F(t) = (delta L)/(initial L) * E * A in other words, (tension) equals (Elastic modulus) times (strain) times (area). I guess that's how I'd find the tension, but what of waves in water, they kinda confuse me. Like an...

ok, that's cool, but what is the *mass/unit of length* measured in? Kg/m, g/cm, does it matter what units I use?

Hi all, my high school physics class has been concerned with waves for some time now. Hoever, we've only considered waves/pulses in strings and cprings, solid mediums anyways. Our textbook has an advanced problem section that asks a bunch about waves in liquid and gaseous mediums--such as a...

ok, I have no idea. If anyone could put this in simple terms it would be greatly appreciated! Thanks

Hi, I've got a question, I recently got interested in piezoelectricity. I almost no nothing about it tho. From the wiki artcile I gathered that when a force acts upon a piezoelectric material and deforms its shape, an electrical potential is created. I know that it has many applications in...

The process known as sampling in reference to music is as follows: A device called a sampler is used to convert an analog signal representing sound waves into digital information. This digital information is called a sample, artists often use samples in their music. however, this not the only...

Can someone define the process of digital sampling for me, perhaps a website with some info on it. I'm writing a term paper and I keep running into sampler adds, but no concrete facts. What is the function of sampler? I'm referring to a device that turns an analog recording into a digital...

that's fascinating. thanks a lot everyone, I'm going to pursue this at best I can. The idea originally struck me as so odd i had to investigate, but i think it would make a nice research topic.

Ok, so recently I've moved on to sound waves in my high school class. I was wondering if sound waves could be harnessed for demolation with accuracy? I was thinking the sound would have to move in a linear vibrational path, without dispersing (making a cone shape), is this possible?
