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!!
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 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.
Why traffic lights are important?
they reduce the frequency of crashes hope this helps:)
If electricity has a frequency of 60Hz it?
If electricity has a frequency of 60Hz, it means that the current changes direction 60 times per second. This is the standard frequency for power supply in North America. The frequency of electricity is important in determining the performance of electrical equipment and appliances.
How does frequency relate to amplitude in the context of wave behavior?
Frequency and amplitude are two important characteristics of a wave. Frequency refers to the number of wave cycles that occur in a given time period, while amplitude measures the height or intensity of a wave. In general, higher frequency waves tend to have higher amplitudes, meaning they are more intense or powerful. This relationship between frequency and amplitude is important in understanding how waves behave and interact with their surroundings.
What is the difference between resonant frequency and natural frequency, and how do they affect the behavior of a system?
Resonant frequency is the frequency at which a system vibrates most easily, while natural frequency is the frequency at which a system vibrates without any external forces. Resonant frequency can cause a system to vibrate strongly if it matches the natural frequency, leading to potential damage or failure. Understanding these frequencies is important in designing systems to avoid resonance-related issues.
What is the resonent frequency of oxygen?
The resonant frequency of oxygen typically refers to the frequency at which oxygen molecules absorb infrared radiation, which is around 60 terahertz. This absorption of infrared radiation is important for studying the atmosphere and climate.
What does household income frequency mean?
Household income frequency refers to how often a household earns income, such as monthly, bi-weekly, or annually. Understanding the frequency of household income is important for budgeting and financial planning purposes.
What is meant by cyclotron frequency?
Cyclotron frequency refers to the frequency at which a charged particle orbits in a magnetic field. It is determined by the strength of the magnetic field and the mass and charge of the particle. The cyclotron frequency is an important parameter in understanding the behavior of charged particles in magnetic fields, such as in particle accelerators.
What is the significance of the plasma frequency in the study of electromagnetic waves?
The plasma frequency is important in the study of electromagnetic waves because it determines the frequency at which a plasma can oscillate. This frequency affects how electromagnetic waves interact with plasmas, which is crucial in various fields such as astrophysics, plasma physics, and communication technology.
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.
