What range of frequencies can be heard by a human?
Hearing Range of frequencies for humar ears if from 20 Hz to 20,000 Hz.
Why do scientists use frequencies in the UHF range?
they use frequencies in uhf range since animals dont make those sounds
What are sound waves with frequencies below normal range?
Infrasounds (frequencies under 20 kHz)
What is the range of frequencies of infrasound?
Range of frequency associated with infrasound is less than 20Hz.
How does the wavelength of a wave change when the frequency changes?
Usually with electromagnetic waves, the frequency and energy is opposite to the wavelength. An EM wave such as radiowaves have huge wavelengths, slow frequencies and small amounts of energy. An EM wave such as X-rays have tiny wavelengths, fast frequencies and large amounts of energy.
What is electromagnetic spectrume?
ALL the radiation from the lowest frequency to the highest.
What is the frequency range of the 3G system in telecoms?
All frequencies are 2-2.1 GHz range
Which type of EM radiation has the shortest wavelength and the most engery?
The shortest wave is a Gamma wave
What type of EM waves do television's depend on?
We would call that "radio" waves. It's radiation (or current in the cable) with frequencies between roughly 54 to 800 MHz. (Wavelengths between roughly 37 centimeters to 5.5 meters.) Not all of this range is allocated to TV, but all TV falls somewhere in this range.
When light from all frequencies of the visible range are combined what is the result?
white light
What is the range of frequencies?
there are an infinite range of frequencies limited only by the mechanical limitations of the medium creating and transferring it.
Is the speed of EM waves as they travel through vacuum directly proportional to the frequency.?
No. The speed is THE SAME for all frequencies of electromagnetic waves.
What range of frequencies can be heard by a human?
Hearing Range of frequencies for humar ears if from 20 Hz to 20,000 Hz.
What frequencies falls in the range of RF waves used by commercial controlled by the?
No frequencies in that range appear on the list you provided with the question.
What is a multiscan monitor?
A Multiscan monitor is a monitor which adjusts to all frequencies within a certain range.
What is a wideband system used for?
A system is wideband when the bandwidth it uses covers a wide range of frequencies. Having a wide range of frequencies available allows one to transmit information on all of them thus allowing great bandwidth.
Why do scientists use frequencies in the UHF range?
they use frequencies in uhf range since animals dont make those sounds
