I was soo confused of the explanation why waves are a circle when looking at phase graphs. Because I have a background in marketing but have to learn about photonics because my company sells photonic devices. And watching your video somehow it's starting to click for me. So easily to understand especially for those new and struggling with this stuff - even for those with an outside background. That's a big compliment and thank you!
hi sir can I know how ur getting the fraction of wave difference???? second example and third example and all u took 7/8 etc... I couldn't understand how it was taken???pls let me know how is it sir....
hi，according to the graph，the fraction of 7/8 could be discovered by comparing the original graph with the displaced one. Tm for original is 4s,the displaced one was moved til 3.5 regarding to the initial position of the original, so 3.5/4 is actually 7/8, hope this comment will be helpful 😂 (tho it’s from 2yrs later )
@@akasun-ds3nb thank you so much. i was figuring a lot how did the author get 7/8 and then i decided to go through the comment and bingo you explain it clear.😅
@@AndyMasley Got it thanks a lot, I just considered it as dividing the entire wavelength to 4 sections, and since the min point was the start and it had just crossed equilibrium, it had effectively covered 1.5 sections. So 1.5/4 when expressed as fraction with whole numbers is 3/8. Does this work as well. Thanks a lot for the videos btw.
Are you sure about the shifting of the waveform about the X-axis (time) when it's a negative phase shift? I might be wrong, but I always thought that a negative phase shift would move the waveform to the right (i.e. any portion of the waveform would occur at a later time). Can you please explain. Thanks!
You won't need to know this for the test, it's kind of arbitrary. I'd say if the phase difference is very close to 2*pi it might be easier to express it as a smaller negative number but that's just vibes
Hello! can we say that if the wave B is shifted -90 degrees or +90 degrees respective of A there is desynchronization? And if the phase difference is 0 degrees there is perfect synchronization between the waves? So it doesn't matter if its positive or negative right? Thank you!
At 4:03 why and how the Fraction of wave = 5/8? I understood that there are total 8 portions in the horizontal number line that's why you wrote 8 in the denominator but why 5 in the numerator? Please expalin Coz I think it must be 10/8. Similarly, why at 4:30 wave fraction is 7/8, it should be 3/8?
Hi, May I just ask about wave cycles. Do we have half cycle or half wave? I mean when we count the number of cycles do we say, for example, 3.5 cycles or should only be 3 cycles and not counting incomplete cycle? Reason why I asked is that I came across an example where half waves were counted as part of the cycle( I used to do this too before) but if I go back to the definition of the cycle and frequency, it says one complete cycle, which made me think that it must be 360 degrees and that is equivalent to one crest and one trough of a transverse wave. Hope to get clarification on this. thank you.
im not hundred percent sure about the circles ting. But im just assuming your mixing interference and phase difference. Even though literally linked. For example for a constructive interference to happen. It must be 1,2,3,4 multiples(probabaly number of cycles). However destructure interference can be anything. Like 0.5, 0.99 and so on
