How many oscillations per second
frequency
The frequency expresses how many complete cycles of the wave pass a certain point every second.
wavelength, amplitude, and frequency
By frequency on the electromagnetic spectrum
Capture the sound with a microphone, feed its output into an oscilloscope with a calibrated timebase. Measure the time period T of the wave on the horizontal axis, then convert it into a frequency ( = 1/T)
To measure the speed of a wave, you multiply the frequency by the wavelength.

You will have to measure it.

Hertz means cycles per second. That is its' frequency.
By frequency on the electromagnetic spectrum
Short wave frequency has a shorter wave length. Frequency is defined as number of cycles per second. If you have shorter waves (measure from peak to peak) you can get more of these packed into one second, so the frequency is higher.
