hi i was just doing summaries for year11 and can some please explain it more to me about complex 3D waves.
also can you explain the graphing of waves to0 me in the whole topic cause im lost.
xD thanks

an example of a 3D wave is sound. it spreads out in all 3 dimensions. compared to a water wave created when you drop something into a pond which is a 2D wave, as it only spreads out in 2 dimensions.

waves are a form of harmonic motion, which i think is a sinusoidal curve. usually they are plotted time vs. amplidude. what exactly did you want to know.

i just want to see a diagram with complex waves in action.
Also i don't get how do you draw waves using the circle of reference

Honestly, why are you still insistent on writing summaries for year 11 . I admire your enthusiasm but you'd be much better off mastering year 12 physics. You're wasting your time otherwise.

As long as you were present in classes during year 11, that should be a solid enough foundation to begin year 12 (IMO) without worrying about the year 11 syllabus, which is NOT directly examinable.

 

[Mr.XClusive]

cause i've havent put much effort in year 11 and shiting myself now cause i don't have a strong foundation. got 68% in my physics prelim exam

 

[independantz]

That, 68% shows you got some foundation and there's no point doing year 11 work in year 12 >.>.

 

[Mr.XClusive]

alright then...i'll still continue to revise year11 work, however i would spend most of my time learning space (last topic i did) and learning motors and generators for my nxt topic. if during my revision i have any problems i would post it on BoS. xD

Just concentrate on the HSC course.

In case you haven't noticed, thats the course that actually COUNTS?!

 

[me121]

You don't need yr 11. You don't need the foundations to succesed. Remember it's HSC Physics, not real Physics so you don't need the foundations, just rote learn everything and you'll be fine. You are wasting time learning yr 11, when you are in yr 12.

nothing in year 11 is assessable and if it is you go back over it in year 12 anyway
