I'm a little confused by how you say minima are created by waves out of phase, because the minima and maxima are both amplified by constructive interference (created by waves in phase), right? And when two waves out of phase by pi meet, then a maxima will meet a minima and cancel each out, not create a minima. Thank you so much for these videos, I just came across them yesterday and they are massively helpful!
Ah right. So on the standing wave created you get zeros if you like at pi out of phase. But on the detectors these would appear as points of minimum amplitude. You are right though they a re nodes.
I liked the activity of drawing circles, it could really help the learners.
The activity of marking interference patterns is intriguing.
Yeah, it's a great one to get your head around the idea.
@@KitBetts-Masters I used it today with my kids and they instantly understood path difference. Thank you.
Thanks for the vid, this was super helpful!
Glad to help!
Incredibly thorough video! Helped me tremendously.
Nice! Glad to help, enjoyed making these videos!
BOOOM
helpful thank you!
Kuru Toga? Nice!
It's the best!
Very useful!
Edit: Boom!
Thanks bud!
What I find interesting is that the interference pattern looks a lot like a magnetic field when you plot all the peaks.
It's a very satisfying pattern.
12:00 isn't pi phase difference 180 degrees

Wierd question but what pen is that?
