do you mean a magnetron?

When the sound wave reaches a very high octave....you can call it microwave.\n\nMicrowaves is used in the hospital to treat kidney stones. It breaks the stones.\n\nAbout weapons? Theres already such weapon..it is installed in a modern passenger ships for prevention against pirate attacks.\n\nWhen the cells are hit by soundwaves??? or microwaves??? it will not be disentigrated but causes some type of damage.

1 microsievert (µSv) = 100 microroentgens (µR)\n\nSo the answer is divide by 100.

i would think that the radiation from the freqs listed above should all cause excite the water molecules in the same way but to differing extents. that's a very good question; i think i'll research it.

I think you may be referring to an oscilloscope.

Piezoelectric crystals will deform when a voltage is applied to them. If the voltage is an alternating one, they will deform one way, then the other way,. If the voltage is alternating rapidly, the crystal will flex rapidly. If the alternating signal is in the audio range, the crystal will emit sound. (Some very small, lightweight headphones work this way.)\n\nThe opposite is true also. When the crystal is mechanically deformed (vibrated), it will generate a tiny voltage. So they can also be used as microphones. Some piezoelectric crystals are actually ceramic materials. \n\nThey will respond at ultrasonic frequencies, and so are used as transducers-- sources and sensors.\n\nThe way the crystal is made inside is that there are layer upon layer of the same kind of molecule lined up, all in the same direction. These molecules are usually polarized, with a free electron on one end and none at the other end.\n\nSo if a thin film of metal is electroplated on both sides of the crystal (and you have to cut the crystal carefully, to make sure you have the molecules lined up right) you can solder wires to those metal platis and use them as electrodes. When a voltage is applied to one side, the molecules want to rotate in place (without stepping out of formation) as far as they can. The electrons repel one another, and this is what causes the deformation.\n\nWhen the polarity of the voltage reverses, the molecules want to rotate the opposite direction (again, without steping out of formation.) The electrons are repelling on the opposite side.\n\nIf too high a voltage is applied, the molecules break formation, and the crystal cracks. The voltage causes a little spark like an electric arc, that ruins the device.\n\nIn addition to the man-made ceramic materials, quartz, tourmaline and Rochelle Salts have these properties. Radio hams use quartz crystals to keep their transmitters on the right frequencies.\n\nIf you are intersted in things of this type, I suggest taking electronics courses. It will be a challenge, but you seem to have an interest, and I know you will enjoy someday being able to build your own ultrasonic devices, like rangefinders and echo-locators. Good luck!

Sure.  An oscilloscope ought to do the trick.

A photodiode will allow current to pass proportional the amount of light incident upon it.

it's sort of like sho-beam, but the sho has a little bit of a z sound.

Well for sund waves you can use the tuning fork and cup of water demonstration. As the water absorbs the sound waves it will ripple with the same vigor as the tuning fork. As far as light waves you can use the same glass and direct a flashlight through it to show how the water bends the light. Hope this helps.

either sound, waves or air.
