Frequency of what?
Different sound frequencies give us music. The world would be a duller place without it.
Different radio frequencies, allow is to be selective in tuning and enable many different wireless connections to be made, without interference.
Different frequnecies of light give us colors. Again the world would be a far duller place without color.
Ans. 2
Frequency, measured in Hertz, in alternating currents, is a measure of the speed of cyclic change in the flow of electricity. AC Electricity in the US is generated at 60 cycles per second (Europe is 50 Hertz). Generators in order to connect to an electrical grid must match frequency with the grid before closing the field switch. Equipment using electricity is designed to operate at 60Hz in the US. Electric motors connected to the grid will spin at a fraction of the cyclic speed (example: 600 rpm, 1800 rpm or 3600 rpm) .
note: Variable speed motors run power through rectifiers to vary the frequency thus changing their speeds throughout a wide spectrum. DC electric motors have independent power sources and can run at variable speeds because there is no alternating current cycle.

What is the sound of glass smashing measured in decibels?
It is not so much the volume of the sound as the frequency as well. Sound at the wrong frequency can be played as loud as you like and it will not break the glass. The sound needs to be the same frequency as the resonant frequency of the glass (tap the glass, that note is it's resonant frequency). Once the resonant frequency has been found, it does not take much volume at all, even humans can do it, albeit trained singers (see Mythbusters).
Hertz Hz is the unit used to measure a wave's?
Hertz means cycles per second. That is its' frequency.
The pitch of a sound wave is its?
Its' frequency.
How does wavelength change when frequency is constant?
the wavelength changes when the frequency changes if the wavelengths are smaller and thinner then the frequency is high, when the frequency is slow then the wavelengths is larger and wider. if the frequency is constant then the wavelength is a normal size
How does the pitch of sound vary with frequency?
pitch corresponds directly with frequency, so as frequency increases, so does pitch.
What factor is important when choosing he ultrasound frequency?
Depth baby!!
Why are lightness important?
they reduce the frequency of crashes hope this helps:)
Why are frequency tables important in every day life?
Frequency tables are important in a variety of ways, and come up in multiple fields. It is important to show how frequent something is done in terms of ordering a product from a company, or when a sports team does something.
What is plasma frequency?
The plasma frequency,(5)is the most fundamental time-scale in plasma physics. Clearly, there is a different plasma frequency for each species. However, the relatively fast electron frequency is, by far, the most important, and references to ``the plasma frequency'' in text-books invariably mean the electron plasma frequency.
Why traffic lights are important?
they reduce the frequency of crashes hope this helps:)
What term refers to the distance a wave travels in a cycle?
The distance a wave goes in a single cycle is determined by a few things. The most important is the frequency, or how many cycles are in a second. The speed of a wave is also important, as it is independent from the frequency.
Is Frequency is the most important factor in achieving training effects?
I would say yes that I think it is but I can't be sure. This is NOT a guarantee but I think that frequency is the most important factor. Again I get a better source than me unless you want to risk it.
Why is lymphatic drainage important in the mammary glands?
becouse of the frequency of breast cancer in the population.
how to do frequency retouch?
photoshop most important application used. frequency retouch photoshop most important application used. and working in photoshop apply, the filter option and blur option apply then professional photo editing service provider company
What is the most important function of ozone in our atmosphere?
The most important function of ozone is to protect from UV rays. these are high frequency waves from the sun.
