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

[@aandm7772]

Honestly, did so much research and could retain anything. First 20 seconds you had me hooked and understood instantly.

[@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

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.

[@Devenderkumar-mk8yw]

Less than 20 hrtz are also known as infrasonic vibrations

[@Emboo_lv]

Mason Klein what’s wrong with that?

[@rahmanaridho]

The one that wrong is the term infra and ultra is used in frequency, in sound named in sonic like : infrasonic, audio sonic, and ultrasonic. In lights : infrared, visible light, and ultraviolet. While sub, trans, super, and hyper are measurement of speed, like subsonic = below the speed of sound, trans sonic = exactly the same speed of sound, supersonic = faster than the speed of sound (usually 1.1 up to 4.9) because 5 and beyond are considered as hypersonic . That's why I feel something wrong with this video and in fact it is.

[@tanisha.6408]

Uhmm...He's a greatttt teacher who made this topic very easier by the example of a loud speaker... THANK YOU SIR!💝

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

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?

[@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.

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?
