I have struggled a lot with this topic but now I have no problems with it. Thank you so much.

[@cheungmarcus9979]

In 15:48 I am convinced that the nodes and the antinodes of the wave in anti phase are drawn incorrectly, they should be the opposite

[@jadewang_z]

So it should’ve been the opposite right? I was so confused when I watched that

provides the sort of depth required to understad the particular topic. A few mistakes just look at the comments below for retification

[@jerryyao8872]

great! amazing! 10/10

[@gahvgs3320]

Straight forward

[@olliejordan652]

At around 9:00, for the waves to become in anti phase from being in phase do they not need to be moved 1/2 an oscillation across rather than 1/4?

[@lak1n294]

yes shes wrong

[@awishjayawardena2308]

since both the waves are moving in opposite directions its actually only 1/4

[@ahmedjahenzaib148]

*waves in open and closed pipes??*

[@salemgelidi3266]

that last question is worded incorrectly. the rope is 7 metres long, that doesn't mean the distance between the two people is 7 metres you would need to have the amplitude of the rope, or the actual distance between the two people to work out the wavelength.

U r good

[@salemgelidi3266]

@@shaukatSciencehub thanks haha i don't even remember writing the comment

[@salemgelidi3266]

@@shaukatSciencehub looking at it now though, I don't know how you could use the amplitude to find the actual wavelength

[@tawanashemakuvaza293]

Fact sure 😀
