Can ultrasonic waves be polarized?
No. Only transverse waves can be polarized Ultrasonic wasves are sound waves, therefore are longitudinal.
How much is about 8 ounces of quartz worth?
It could be worth nothing or a great deal - depending on the form it takes. Compare a perfect 8 oz. Herkimer quartz crystal versus 8 oz. of silica sand. Great difference in worth. Quartz is the most common mineral on Earth, so when dealing in ounces only a good specimen will have value for the most part.
What is blue quartz rock?
It's a type of quartz rock, only it's blue.
What is the atomic number of quartz?
Quartz is a compound, specifically silicon dioxide, and compounds do not have atomic numbers; only atoms do.
Is there such thing as a black topaz?
No. there is only smoky quartz
Where can I find a CRYSTAL BALL in NYC?
If you are looking for a REAL Crystal Ball cut from quartz or other gemstones, rather than just a glass sphere, check out ROCK STAR CRYSTALS. They not only have real quartz crystal balls in a wide variety of sizes and prices, they also have the largest selection of gemstone spheres in other minerals in NYC!
What are the modern methods to produce ultrasonic waves?
A piezoelectric crystal gives off electricity when compressed (used in gas grill igniters) but will also change volume when an electrical current is applied. When a high frequency alternating current is applied to the crystal, it expands and contracts at the same frequency as the current. If the frequency is high enough, it produces sound waves above the range that people can hear- ultrasonic.
How many different quartz are there and what are they?
Quartz has many different habits, but only one crystal system category, trigonal, and one formula, SiO2. The various forms of quartz are a product of their method of formation or exposure to radiation or impurities. Some forms are agate, chalcedony, jasper, amethyst, chert, rose, citrine, smoky, milky, moss, flint, Cat's Eye, Tiger Eye, prase, carnelian, rock crystal, and aventurine.
Can ultrasonic waves be polarized?
No. Only transverse waves can be polarized Ultrasonic wasves are sound waves, therefore are longitudinal.
What are the powers of a Rose quartz?
Quartz is the second most abundant mineral in the Earth's continental crust after Feldspar. It is made up of a framework of silicon-oxygen tetrahedra SiO4, with each silicon shared between two oxygens to give the overall formula SiO2. Quartz has a hardness of 7 on the Mohs scale and a density of 2.65 g/cm³. Quartz belongs to the rhombohedral crystal system. The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end. In nature quartz crystals are often twinned, distorted, or so intergrown with adjacent crystals of quartz or other minerals as to only show part of this shape, or to lack obvious crystal faces altogether and appear massive. Well-formed crystals typically form in a 'bed' that has unconstrained growth into a void, but because the crystals must be attached at the other end to a matrix, only one termination pyramid is present. A quartz geode is such a situation where the void is approximately spherical in shape, lined with a bed of crystals pointing inward. Quartz crystals have piezoelectric properties, that is they develop an electric potential upon the application of mechanical stress. An early use of this property of quartz crystals was in phonograph pickups. One of the most common piezoelectric uses of quartz today is as a crystal oscillator. The quartz clock is a familiar device using the mineral. The resonant frequency of a quartz crystal oscillator is changed by mechanically loading it, and this principle is used for very accurate measurements of very small mass changes in the quartz crystal microbalance and in thin-film thickness monitors. No scientific evidence has been presented that quartz has any other "powers" to speak of. Rose quartzes are good for absorbing negativity in a room or on a specific person, and for repairing the heart chakra. QUARTZ CRYSTAL, Rose: Attracts love; Creativity; Comfort; Companionship; Eases tension; Emotional healing; Happiness; Increases self-assuredness; Love; Opens heart chakra; Pacifier; Peace; Promotes peace, happiness & fidelity in relationships; Reduces weight & wrinkles; Self-confidence; Stimulates love. Used in an elixir for self discipline and responsibility.
Will quartz dissolve in acid?
Quartz will only dissolve in hydroflluoric acid.
Can ultrasonic wave pass through 1Cm thick iron plate?
Yes. Ultrasonic waves can pass through metal. The only difference between "normal" sound waves and ultrasonic waves is that we cannot hear ultrasonic waves. However, they behave the same.
What processor used in watches?
It depends on the complexity and functions of the watch.A basic quartz timebased watch only requires dividercircuits, to generate the 1 Hz pulse from the high frequency crystal oscillator.
Why are quartz watches so accurate?
bcoz as d electronic watches now available use vibration of a crystal of a substance called quartz to mesure time . d frequency of da vibrting quartz crystal in side these cloks n' watches is so regular dat dey lose or gain only 1s every10 years......to take mor information go to SHARMISHTA MAAM OF CLASS 5B DPS KALINGA ODISHA.....BY KALPAM NAYAK class 7aDelhi Public School Kalingaodisha

Is Ultrasonic Food Washer Safe?
It's not only safe it's very healthy to clean your vegetables and fruit with a ultrasonic food washer. It can help clean soil and pesticides and any other matter. Ultrasonic cleaners only use high speed vibrations no chemicals.
What is blue quartz rock?
It's a type of quartz rock, only it's blue.
