Why do scientists use frequencies in the UHF range?
they use frequencies in uhf range since animals dont make those sounds
What are the two main bands of television wave frequencies?
Amplitude and frequency
What are two main bands of television wave frequencies?
Amplitude and frequency
What are two things all waves have in common?
they all have amplitudes and they all have frequencies.
Two sound waves of the same frequency can interfere with each other but two sound waves must have different frequencies in order to make beats. Why?
To alternate between constructive and destructive interference requires different frequencies.
Can you use 80211n router for 802.11g adapter cards?
Yes, almost every n-router available supports b and g-modes too.
Why two frequencies are used in dtmf?
The tone frequencies, are selected such that harmonics and intermodulation products will not cause an unreliable signal. No frequency is a multiple of another, the difference between any two frequencies does not equal any of the frequencies, and the sum of any two frequencies does not equal any of the frequencies.
What frequencies do radar detectors use?
Radar detectors don't "use" any frequencies. However they listen to certain frequencies known as bands(K, Ka, X, Ku). These bands are the frequencies allocated to radar guns to operate on.

What is are unlicensed radio frequencies?
Those which you can use for free, for instance a tv remote control uses such frequencies.
What frequencies do British police use?
999
What types of diodes are used in high frequencies?
Two types used at microwave frequencies are gunn and PIN diodes.
Why do we use high frequency waves as carrier waves?
The use of high frequencies for carrier waves in communications permits a higher rate of information transfer than could be accomplished with lower frequencies. The higher frequencies have the potential for higher "data density" or "information density" than lower frequencies.
What causes beats?
Two frequencies of sound that are constant.
What type of frequencies do bats use for their radar?
ultrasonic
What freqencies does a AM radio use?
AM radios can use frequencies in the range 535 kHz to 1605 kHz. Frequencies are assigned at 10 kHz intervals, from 540 kHz to 1600 kHz.
Why 50hz only not other frequencies can use?
There are other frequencies, such as 60 Hz, 25 Hz, and 400 Hz in common use. Please restate the question - it does not make sense.
