Okey I've read some comments + this article Khanacademy link. Just like you said. I tried to understand it again, but I don't know if what I will say now is correct. I'll use some picture for it.
I'll try to explain some stuff of what did I understand. If you could if it's okey...
@sophiecentaur
I mean I just got confused.
Many stuff just mixed up in my head and I don't know where to start again.
In the topic there is also everything a bit mixed. Or maybe I read it wrongly some comments.
How light works maybe easy but I just get confused of overflowed information I...
I said introduced it saying also about the multimode fibre :
I just wonder what I'm doing wrong then.
All I really know is that there is one source that is for example a laser. In the video of splits into two sources that are the same. Same phase same wavelength. They interfere with each...
@sophiecentaur
I thought of the intensity of this bright points in the screen as an essential so I was asking.
I'm sorry I usually find something that isn't covered in the basics so it's confusing for me.
Because when there are 2 different wave lenghts then I thought that they don't interfere...
@sophiecentaur
I don't really understand it is it possible to give a sketch of how it looks like ? Difference in the path doesn't tell me alot, but okey let's say there is this difference in the path.
Usually when there is interference then +1 peak lines up with +1 peak or +1 peak lines up...
@sophiecentaur
Yes I have I guess understood the impotance of + and - sings. But I didn't understand why is it shifted in phase even though they are in phase so they should be increasing ?
I mean here is also shifted in phase waves :
Because those waves can meet each other like that if they...
@sophiecentaur
So let me use paint as a my understanding point :
in this picture there is an interference.
On the screen I can have +2 colored by green dots or I can have less but still increased colored by blue let's say it is +1 or 0.
So at the end of this interference from this video...
@sophiecentaur I don't know if I conveyed exactly what is my problem but I slowly am getting how things works.
I just don't get what happens if we have not the peak of waves but something in between ? Like peak wave lines up with not peak. Or why peak of the wave lines up with the valley peak...
What I meant is that the wave is a sinusoidal so the peaks are at certain points but those waves have also spots where there is no peak like here :
I've used the red color to show it. It is not the peak it is something between the peaks.
And I was wondering what happens if not a peak lines up...
I've watched it, some of the things he had mentioned was very interesting like this :
I've added one element (in red lines) this isn't the peak as I know right ?
So what if a peak lines up over a not peak then something can happen ?
Also as I can understand from this picture is that it is the...
Okey so correct me if you can @tech99 and @sophiecentaur
From this :
I understand I guess that multimodule gives more "paths" for single light in which this single light is bouncing from one side to another.
I don't understand the moment with the power light.
Also the delays does it mean...
@tech99
Why is that whey pass each other without interference ?
Doesn't it work like here ?
Like they interfere with each other and at the end we see the new stronger wave at some point and weaker at the other point ?
Why the same wavelenght can interfere but different wavelength can't ...
PS.
Here is also what I mentioned about connecting many source of light into one :
It is from my university lectures. So there is only a photo.
I mean I get confused when it comes to this interferation effect, and if it changes anything here ...
Sorry for my confusion it is just that one...
