Bruh why youtubers better at teaching then my teachers

[@inasakusina4345]

Well explained! I just need something like this in my class. Thank you so much.

[@pratibhajodhaJodha]

Thank you so much ma'am every concept is crystal clear

[@ghostofrhys]

why is cornelius acting like a statue at 7:33

[@ifeanyichukwuidoko6599]

Nice illustrations. Thank you.

Me: sitting 2 weeks after my work is due at 10 pm watching this for homework

Super explanation I love 😍 it

Hi GPB Education. I have two identical speakers connected to a computer playing the same song. I did placed the two speakers opposite from each other and 90 degree from each other but I did not get destructive interference. How do I position the two speakers so that I will get 100% destructive interference (no sound or almost no sound) ?

Love the energy 😍🤍really thank u for this video

[@GPBEducation]

Thanks for watching!

[@chrisgrimstad9985]

my jaw dropped when she explained beat frequency 7:32, so cool

[@ariskhan2903]

excellent video

[@Saxyct]

Who is the speaker? she is not among the teachers listed in the website

Hello, what I really wonder is how we can obtain the attenuation in two waves after having the interference?

[@JiihaaS]

Mathematically, when the waves are identical but 180 degrees out of phase, they are in fact each other's negative counterparts. In physical terms, when the other wave creates an increase in air pressure, the other creates an identical amount of decrease, and vice versa, resulting in no change of air pressure = no sound.

Amazing explaition

[@vivwins]

yo how is diffraction defined in this video

[@kaik3122]

@Julian thx bruh

[@vivwins]

Julian thanks julian ily

[@tomkot]

How do you calculate how much a sound wave of a given frequency diffracts?

[@alexlai6556]

very good explanation, why so few likes

They don’t ‘bend’ ... they reflect.

hi tillie

hi orelia!

[@tilliemargulies8501]

workout?

[@djphylearninglake7172]

"bending" does not make much sense

[@ChiDraconis]

*I concur* Given an isolated table-top demonstration a "beam" of sufficiently narrow focal tightness should display backscattering which should show that "light" it the normal senses ( rainbow) is only narrow spectra with hard backscattering such that Rutherford backscattering spectrometry would display on-beam lambda within 0.04 degrees of neutral axis displaying the most conserved tensor with a neutral at 90° then reduction of "frequency" toward near-zero in the backreaction

Don't believe everything you see on KZbin!! The thunder high crack - low rumble phenomenon is a better example of the atmospheric absorption of sound than of the diffraction of sound. Lightening in the desert or on the plains will still sound low when it is further away even though there are no obstacles (diffraction) between your ears and the source. Atmospheric absorption is based on a combination of viscous & thermal conduction effects as well as molecular relaxation processes. The attenuation curve is roughly the square of frequency. See: ANSI standards S1-26:1995, "Calculations of the Absorption of Sound by the atmosphere" (ISO 9613-1:1996) andH.E. Bass, et al, "Atmospheric absorption of sound: Further developments", J. Acoust. Soc. Am., 97(1), 680-683 (1995).
