What is a phase difference? (physics, waves) :(
étudiante
étudiante
haha! sure!
phase difference is like how much one wave is forward or behind another one... like if one wave is on the top and the other one is down, they have a phase difference of 180 btw dem :)
$~SauD~$
$~SauD~$
if the passing together?
like if the crust of the first wave is on the trough of the other wave then what is the phase difference?
étudiante
étudiante
u mean super-position?
if the crust n trough are on each other den its still a phase diference of 180, but they can superimpose n den u'll get a str8 line :)
$~SauD~$
$~SauD~$
No what is phase difference? when does it happens? how to calculate it? and :/ :/ :/
étudiante
étudiante
see phase diff is basically how much one wave is behind another, measured in radians :)
it happens whenever there are two waves.... its just like say ur walking behind someone n i say ur walking 2m behind him... same way, i'll say dat this wave is 180o behind the other :)
can u show me a question or something? den it'll be easier to explain how to calculate :)
$~SauD~$
$~SauD~$
only behind? what if up or below? :)
cool explanation but i didn't get much :(
Wait one sec :)
étudiante
étudiante
same thing even den ;)
it was stupid sorry! :oops: wait lemme think a min...
sure tyt :)

it was great :) but i didnt' get :(

@question... phase difference isnt exactly "calculated" more like inferred....
so u can see that X and Y are exactly the same distance from the ends of the wave BUT one is up n 1 is down, so this is a phase difference of 180 since they are opposite
étudiante
étudiante
wat u basically need to know is that if they are exactly opposite den dey are 180 out-of-phase, if same postion but different waves then no phase difference, and quarter cycles can be 90 or 180 depending on the wave given
(dat was confusing i guess... see the vid btr :()
sorry m so crappy at this :,(
$~SauD~$
$~SauD~$
what will happen if both points are on the same line? :)
or have different distances from the ends?
$~SauD~$
$~SauD~$
you are not crappy... this thing is crappy :(
étudiante
étudiante
it will either be quarter or three quarters away (90 or 270) u wont get nething in btw dw :)
both are >.<"
$~SauD~$
$~SauD~$
won't the same like make it zero????? :/
no >:*(
étudiante
étudiante
yes it will :) its difference, so if dey r exactly one wavelength apart den dey will be 0 phase difference.... did u watch the vid? m so awkward at explaining dis sorry! :S
$~SauD~$
$~SauD~$
i will wait :)
but what if more than one wavelenght? like 1.25 wavelenght apart? :D
étudiante
étudiante
dats still a phase difference of 90 degrees because u ignore the full waves (dey r phase difference of 0 neway)
