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.

What are sounds with frequencies below 20 hertz called?
Infrasonic.'Subsonic' and 'infrasonic' both define sound too low (in frequency or pitch) to be heard by humans without assistance.However, as 'subsonic' can also mean something traveling slower than the speed of sound, and 'infrasonic' only means frequencies below the audible range, 'infrasonic' is the better answer.
What is the difference between infrasound and ultrasound?
Ultrasound is above 18 kilohertz. Infrasound is below 20 hertz.
What is different between infrasound and ultrasound?
Infrasound is sound that is lower in frequency than 20 Hz (Hertz) or cycles per second, the normal limit of human hearing. Ultrasonic waves have frequencies above the audible range at around 20 kHz. Audible sound is within human hearing range.
What happens to the upper limit of your audible range as you age?
It decreases from 20,000 downwards
How does the pitch one can hear vary with age?
The upper limit of audible frequency commonly decreases with age.
Which one of the following frequencies of a wave in the air can be heard as an audibke sound by the human ear?
The human ear can detect a wide range of frequencies. The lowest frequencies are around 16 to 20 Hertz while the highest can be as much 20,000 Hertz. As we get older, our high frequency limit tends to reduce so an older person may only hear sounds up to around 15,000 Hertz.
How many different types of sound are there?
All sound is the same, just at different frequencies and volume. However sound is often categorised into three groups. Subsonic - Low frequency, below the threshold of human hearing. 25 hertz or less. Audible - Any sound a normal human being can hear. 25 Hertz - 18 Kilo Hertz. Ultrasonic - High frequency sound, above the threshold of human hearing. 18 Kilo hertz and above. It should be noted that some animals such as dogs and bats can hear much higher frequencies than humans. Also note, the upper limit of human hearing varies from person to person, and decreases with age. 18 - 18.5 kilo hertz is normally the upper limit for most people.

Which electromagnetic wave has the lowest frequencies (less than 3...10 hertz)?
The lowest frequency is that approaching infinitesimally close to the DC limit of 0Hz.
What are the highest-frequency and the lowest-frequency parts of the em spectrum?
-- The lowest frequencies that we have a name for are what we call "radio" waves. -- The highest frequencies that we have a name for are what we call "gamma" rays. Although there is not upper or lower limit in the electromagnetic spectrum.
Which electromagnetic waves have the lowest frequencies?
"radio" there is no real lower limit (in theory).
