Sound: Wavelength, Frequency and Amplitude.

NOTE: Subsonic and Supersonic are old terms and more commonly refer to speed rather than frequency. In modern use, “infrasonic” refers to frequencies below 20Hz, while “ultrasonic” refers to frequencies above human hearing.

KS3 Science video on sound. Topics covered: transverse and longitudinal waves, wavelength, frequency, pitch and amplitude

[@Potato-nc2jp]

Notes: Each wave is one pulse The number of pulses is the same as the frequency, the amount of hertz, if there are 4 pulses then the sound is 4 hertz The graph is measured in a certain time frame, for example in a one second graph if there were 4 pulses then it would be 4 pulses per second and a frequency of 4 hertz If we have a longer wavelength then that means we have fewer pulses which means lower frequency and a lower pitch If we have shorter wave lentgth it means we have more pulses which means higher frequency and higher pitch Height of the wave tells us the amplitude Higher amplitude means higher sound and vice versa

To clarify, the reason sound waves travel faster in water is relative to the bulk modulus, not the density.

[@akeverywhere7355]

[@user-kc1vg3nt2o]

Good video but I would make the following changes. Waves with a higher frequency than what we can hear are ultrasonic. Waves with a lower frequency than what we can hear are infrasonic. Subsonic and supersonic refer to objects travelling faster and slower than sound.
