Best explanation, thanks!
What happens to the light rays interfering destructively? Their paths just
so happen to cross. Do they continue their trip through space as if nothing
had happened?
lol you still can see a smiley on the left hand :D
Dude you are so funny :’D
I just love how you explain stuff with a empty paper :). Thank you very
much for this contribution to help me study :)
Barney Stinson? Is that you?
this was a great explanation 🙂 thanks!!
I have my Optics exam in 2 days…thanks for making this fun :P!
hi ummmm i really like your video
it s helping me out do this experiment for this physics competition
i was just wondering where i could get that small square plastic thingy
with a lot of slits that you showed on the video
could you tell me what the name is?
Suddenly a wild marker pen appears at 11:40….
I love this guy. Fun to learn.
Hi, thanks for the video. You are a great educator.
Around 6:58 you mention that the angle between the normal to the first slit
and the diffracted ray from the first slit is equal to the angle between
the normal to the first diffracted ray and the line containing the slits.
We can see this intuitively, but is there a specific name or term for the
argument which proves this equality?
Hello! Um, in the last video you said that black fringes are formed when we
have a trough on a trough. This means that we get dark fringes too when
there is constructive interference? Doesn’t this video then contradict the
results of the previous video? There we got dark(black) fringes upon
constructive intereference and here we are getting them upon destructive
interference..i’m confused 😐 btw amazing videos, you’re easily the best
physics teacher on youtube!
do you know how many lines per mm were on the diffraction gratings you
used?
and i was also wondering why the circle forms…could i have an explanation
for that?
Hey Doc, amazing video. I definitely learned a lot in these 17 minutes.
I just have this one doubt.
See,you said that the light waves(let’s call them waves) coming out of the
slits were spherical. But shouldn’t they be forming a cylindrical wavefront
according to Huygen’s Principle?
Please just explain this.
Loved the video. Instant subscribe!
i think it is (n+0.5 λ) than (n-0.5 λ)
Am I the only one who thinks he sounds like Barney Stinson from How I Met
Your Mother? Thanks for the upload, easy to understand, now I can finish my
physics hw.
Fun way of teaching man!!I wish all teachers would adopt yours way of
teaching then learning could really be fun making.And I wanted to know
bright and dark fringes have certain length or they are just points??You
havent talked about that!
Amazing how much I can absorb when the lecture is not boring. Thanks!
I freakin love this doc.
Thanks for your wisdom.
I have already learned many of the things you teach but you just make it
click!
In the video you mentioned the rays would be in line, they could also be in
phase.
one question: where do you put your camera when you´re filming?.
:)
thanku so much…..most nyc explaination ever………
How did Young managed to make such small slits. I mean 10 to the -6 m.
Thousand times smaller than one milimeter…
