The Wavelength, Frequency, and Amplitude of Sound _ Knowledge Platform

Objects that vibrate in some medium create mechanical waves known as sound waves, which propagate through that medium as vibrations of the individual molecules. If the sound wave enters the ear canal, it will eventually reach a thin membrane known as the eardrum, which will vibrate and in turn cause the three bones (malleus, incus, and stapes) to vibrate. This will ultimately send a signal to the brain and we will perceive the sound wave as sound. So sound is simply the way that humans and other animals perceive sound waves. Sound waves can propagate not only through the air but also through other mediums such as steel, glass, helium, and water. In air, the velocity of the sound waves depends on temperature and is given by an equation as described in the lecture. Whenever we describe sound waves, we usually mention the loudness and pitch of the sound waves. Loudness and pitch are subjective properties and depend on the intensity and frequency of the sound wave, respectively. The higher the intensity (power out put of the sound wave per unit area perpendicular to the movement of wave), the higher the loudness and the higher the frequency (number of complete oscillations per second), the higher the pitch. A good human ear is capable of detecting sound waves whose frequency ranges from twenty hertz to twenty thousand hertz. This range of frequency is known as the audible frequency range. A frequency above twenty thousand hertz is known as ultrasonic sound while a frequency below twenty hertz is known as infrasonic sound.Transverse waves, longitudinal waves, medium, compression, rarefaction, wavelength, amplitude, frequency, crest, trough.

A great platform for solving basic doubts. 👍🏻

[shabbirmaster]

I mean the explanation is good, but people watching these could be high schoolers not toddlers

[pavithrasg]

Really helpful for exams love ur teaching way

[hoorlaraib]

it is quite a perfect way of teaching, and it is useful for exams. hehe lolz but I appreciate the hard work

At the very last you said longer wavelengths is similar to higher frequency. I am confused in this. Higher frequencies mean your wavelengths should be small, since they are inversely proportional to each other. Correct me if I am wrong.

This vedio clears my all doubts n it helped me a lot thanx for it ☺☺

[prajwalchandak]

I really liked the voice its like Doraemon so I was imagining like he is teaching me. ❤️

[fitedu-club]

the teaching method is sooo simple and good anyone can understand, thank sir g

[ManpreetSingh-Ind]

I am to thankful to you for this beautiful explanation. Listening to this got me back my school days, the explanation was so crisp. Specially the part about Light coming in first before sound of a thunder

[qt-criptic]

omg i have a test tomorrow and this helped so much

[RaghuRam-zdtn]

Wow, it's amazing video. Nice Explanation

[pakistank]

Thank you👌😊 Great W0rk❤🇵🇰❤👌👍👍 & Well Explained👌😊💚💚🇵🇰🇵🇰

The maximum distance of a wave's crest or trough from its undisturbed or rest position.

[shruthicashan]

Hereafter, I will refer you for exams

[Viexcee]

Who are watching this while quiz, seatwork, or exam?

It sucks we can no longer tell which video is good, which one is I need the dislike stat back to the people.
