What is the highest and shortest frequency waves?
There is no absolute limit on frequencies. The frequencies can be almost arbitrarily small or big.There is no absolute limit on frequencies.

Frequencies to low for people to hear are called what?
"Subaudible" frequencies.
Which phenomenon occurs when one wave is superimposed on another?
Beats are formed. The number of beats heard in one second will be equal to the difference in frequencies. If the difference is 4, then 4 beats will be heard in one second. If 1/4 is the difference in frequencies then 1 beat will be heard in every 4 second.
If 20 beats are produced within one second which of the following frequencies could possibly be held by two sound waves traveling through a medium along a common path at the same time?
The frequency of the beat is the difference in the two frequencies involved, so you need to check which pairs of frequency have a difference of 20 Hz.
At what frequencies do advertisers concentrate the commercials sound?
At frequencies in which the ears are the most sensitive.
Two sound waves of equal amplitude with slightly different frequencies will result in?
A beat frequency.
What beat frequency is produced by two tuning forks that vibrate simultaneously withe frequencies?
3.0 HZ
What are oscillators used for?
Signal generators: reference (tuning equipment) source - such as electronic keyboards beat frequencies - as in a superheterodyne radio

Is am frequencies higher then FM frequencies?
no
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 is function of an oscillator?
A local oscillator is an electronic device used to generate a signal normally for the purpose of converting a signal of interest to a different frequency using a mixer. This process of frequency conversion, also referred to as heterodyning, produces the sum and difference frequencies of the frequency of the local oscillator and frequency of the input signal of interest. These are the beat frequencies. Normally the beat frequency is associated with the lower sideband, the difference between the two.
Which frequencies are the airband frequencies?
Airband, a group of frequencies in the VHF radio spectrum, uses the frequencies between 108 and 137 megahertz. A license is required to operate airband equipment.
Frequencies to low for people to hear are called what?
"Subaudible" frequencies.
Do hearing looses develop at low frequencies faster or slower then they do at high frequencies?
The high frequencies suffer first, with age.

Can A standing wave can only occur at natural frequencies?
A standing wave can occur only at specific frequencies that are called natural frequencies.
