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

[@erikadorsainvil3251]

Hello, What would be a good question to ask for a second grade science fair project using the gummy bear wave machine in regards to sound? What kind of graphs could my second grader make? I was thinking to measure how fast the wave comes back to the starting point when we add energy to the wave machine. Repeat this procedure 5 times taking 5 gummies off each time until i reach the mid point of the gummy wave machine. What do you think?

[@rikmang]

How is that I can put a whole song together in my mind .but there is no sound or vibration or frequencies bouncing in the air or eardrums? If sound is vibration only then what are thoughts or words in your mind?

[@tomschwiehn]

This was a very good explanation! Than you!

[@joshuaarnold8579]

Dude I'm so thankful for this video. This made my day . So easy to understand. Keep it up :)

[@moondive4ever]

Facts!

[@jasnoor8-d-155]

Hey in my book there is that loudness is proportional to the square of the amplitude is it directly or indirectly proportional or we put it in equation as
L=A^2 ?
I would really appreciate if you answer my query

[@akeverywhere7355]

Very Informative and helpful

[@aceways4771]

This is fantastic. You’re really great at explaining and keeping us engaged! But I’m confused on wavelengths, im studying audiology and they say wavelength is one mountain top to the next, but yours starts on the middling and does a full mountain and valley. It’s twice as long and what my course would call a ‘wave cycle’ so now I’m really not sure which is right. Is it either?

[@Science_Sauce]

Both are the same - if you pause the video and measure peak to peak, then measure midpoint to midpoint it will be the same length. Trough to trough also works. One cycle = one wave.

[@ayutty7441]

[@bluephoenix372]

Im going to get an air physio, it supposedly causes a vibration in the air which loosens mucus in the lungs... would this be a resonant frequency of the air vibration acting on the mucus increasing its amplitude and therefore vibrate harder which causes it to shake apart?
