Sound and Vibration in Solids and Liquids

11/05/2015 10:34 AM

Well, i'd like to reiterate my query.

Say I am a fish which is sensitive to sound and I'm about 5m away from the droplet. Which will arrive to my attention first, (the sound of the droplet or the first wave in motion)

Now, I made possibly make my point clearer.

The speed of sound in water is 1482 m/s.

What do you think will arrive first? Why?

What is sound? Can you give me your definition?

Obviously, the sound first before the first surface wave.

Sound is a mechanical vibration in the realm of 20 to 22KHz bandwidth to us humans.

I have a wrong thinking before. I guess now, i see a little bit clearer on the subject.

Others might see it as well and confirmed, I am not the only one misguided by an assumed fundamental learning.

I wont probably tell enough, unless others could tell the difference.

Waves in general are confusing and complicated to understand.

Study the difference between what may loosely be called dispersion and compression waves in a medium.

If the fish can see the droplet as it hits the water, the light will travel faster than the sound....

If you read the first answer to you first post you wouldn't need to reiterate.

What's the point of asking Qs if you don't listen to the answer?

THE SOUND AND THE VIBRATION ARE THE SAME THING.

Certainly, but vibration is little bit broad, you know. There are 2 types of vibration produced by the simple droplet phenomena. Their mechanics is probably different from one another and its pretty interesting to find.

Here's an idea, how about you going back to school and start with learning how to do your own internet researching and taking some remedial physics courses?

Problem is, fish don't have much for brains and no ears.

There's 2 types of idea

  • Your idea
  • My idea

Now, what's the probability proportions selecting 1 from the 2 choices?

I say, definitely, not 50%. Then the books were mistaken and also, the model.- Schrodinger mess it.

You are missing at least a third option: Their idea.

This widens the probability to 1 in 3.

If we factor in the possibility that all of those three are wrong then there is a fourth option: None of the above.

Or; If we factor in the possibility that an unknown part of each idea is correct we now have the fifth option: Some parts of the above.

Now we are beginning to approach reality and have 1 in 5 ratio with a high probability that the "real truth" is an unknown combination consisting of minute portions of each idea.

Hence: The reason why teams of competent, unconstrained, intelligent, free thinking individuals with small egos are far better at solving problems and accomplishing great things than one or two egotistical individuals.

Wonderful reply. Perfectly explains both the appeal of IHS and the repugnant nature of the lurkers with the giant ego complexes. To be part of a curious intellectual discovery group while trying to avoid dreaded "you are not worthy" ego driven group is tedious and destructive to creativity. But hey, it's free, and the potential upside usually outweighs the disadvantage of annoyance. You guys are fantastic.

Real problems are not all found in books, some left unsolved in the real world even today and the up coming centuries.

How many discovered laws are there in Physics - few

How many theories are all there is - many

Therefore, don't tell me you have confidence telling people what to do and how things should be. Theories are not reality, at all - out of the box.

I would suggest that there are many more than 2. You have yourself already agreed that there is at least 3.

Oh really.

That's news to me but a search does agree that this is a misattribution to Einstein. It seems the first time a similar phrase was accurately quoted was in 1986 by Tony Elliot of the New Orleans Saints. "the definition of insanity is doing over and over again things that can kill you" [9]

Live and learn.

Any athlete knows that doing the same thing over and over is the primary way to improve (get different) results. In science, your ability to change tiny inputs may make it appear to the uninformed that you are doing the same thing over and over. For instance, asking the same question to a new group of respondents may get you the same answers, maybe not. BTW, Einstein did not say that.

From experience I can tell you that the noise from an underwater blast is realized by humans before the shock wave is felt.

From experience, inside the hull of a ship, you can hear the "Tick" of the fuse going off before you hear the main blast, followed by the shock, of a depth charge.

Then you can predict the distance of the charge and the intensity of the blast from a far?

It is more outstanding if you know where the next drop splash is prior to detonation.

Ok, enough stuff. The guys from the agency are probably agitated.

Of all the fish that you could be, you'd likely be a Bass, and climb out on a big old rock and slide down on your face.

Or, if you like Perch, you could perch on this......Holding middle finger vertically.

One would assume the fish would see the waves of motion well before they got to him. Most seem to have a rather wide field of vision, and since light travels much quicker.....

Still have a problem with the question. Differentiation between sound and waves not withstanding as an issue, which unfortunately it is, you should have had a blind fish at 5M....
