Grating problems. These kind of problems in higher education which have a method like usual study problems or sometimes a bit of difficulty level is a test for knowing the problem solving ability. It is not about concepts always. Being able to solve study problems is a good sign for getting a university degree in education in the sense of skill. Thanks.
Hi, great vids! Quick question if d=1/N , N = number of lines per meter ,for example, d= slit spacing… then are we counting the end edge of the diffraction grating as 1slit? Take a diffraction grating of 1m with one line ( slit) in the middle, we know slit spacing is 0.5 m … we know there are 2 slit spacings & 1 slit. But applying the formula without counting end edge as 1 slit we get o.5 = 1/1 … instead of 0.5=1/2 ( counting the end edge as a slit. ) I hope this makes sense.. thanks 🙏
(c) Another diffraction grating has half the angle between the first and second order light beams when light of wavelength 532 nm is incident upon it. Estimate the number of lines per mm of this second diffraction grating. [2] The initial grating has an angle of 7.8 degrees difference between theta 1 and theta 2
What the hell is this like n=length/no of lines so how this n suddenly equals to 1/d ???? What's this ?can you please reply me because may be my concept is built wrong.
at 1:10, does "m" correspond to minimums or maximums? because m0 seems to be at the central maxima, however m1 and m2 seem to be minimas. Could someone please help me out.

Guys most of us owe our lives to this dude, you're a gem man. Thank you, God bless you and keep making these vids cause we love them. Peace
Facts bro
I don't owe my life to him.
YOU ARE A SAVIOR YOU SAVED ME IN MY ORG CHEM AND NOW YOURE SAVING ME IN MY PHYSICS
This helped so much! Can you please make a video about thin film interference
you are a veary talented teacher i only understand physics from you thanks a lot :)
this man's saving my Waves and Light test, an absolute godsend
Thank u you ARE MY TEACHER REALITY
Loads n loads of thanks, u made my day , I was struggling with this question ❤
Kinda same here ☺️
Are you preparing for ATC?🙄😁
Thank you for making this and other videos. Really helpful for a faoundation student like me. Thanks again !

This is exactly the video I was searching for
Thanks bro
I wish you were my physics 3 professor for next semester
You're such a blessing ❤️ ❤️❣️
Beautifully explained sir.....
Thank u so much JG for all ur videos
Omg thank you so much, why couldn't my teacher just do this instead i got them all right after you did the first one
Thank you so much! This is a life saver
mantap geng
I love man... Thanks!!!👏👊
enjoying the lecture it's so helpful
thank you very much. your video are very productive.
You are awesome man. Always appreciate these.
Still using these videos!
Thanks for the tutor
idk but I'm attracted to this man lmao
man you make really good videos
THANK YOU❤
Thank you.
Than you so much ...it helps a lot 😍☺️
that was very helpful. thanks.
Thanks 👍
Literally watching this 20 mins before my test
Thank you Sir🤝. Can u please make a video on special relativity?!🙏
Very helpful , THANKS
Thank you so much ❤️
Amazing 👌
Thank you so much
Thanks a lot man....it really helped 👌👌

thanks a lot!
Could make to find the total number of orders of diffracted light? Should the angle be Zero? (dsine 0= m lamda?)
the second question u did the wavelength did not fall in the visible range - so how can we see the interference pattern?
How would the math change if the slits weren't all evenly spaced?
Error in defining 'd' at 1:27.
can you make a vedio about poetential and voltage dividers please???!!
What is the distance between fringes produced by a diffraction grating having 139 lines per centimeter for 590-nm light, if the screen is 1.50 m away?
Pls I think there’s a mistake with the conversion from centimeter to meter cos while solving am getting a different answer from yours.
im getting 100 he made a mistake
can you do some overlapping problems?
is it m lyamda in both bright and dark frindge?
I used to be HELL scared of diffracting gradients. Man those were really easy. Trick is to not be intimidated by the question.
Hi , sorry I’ve always been confused by the formula d=1/N … see previous msg .. thanks
isn't cm to m Divide by 100? Then why you multipled by 100? stucked please reply
yes. To convert cm to m, you need to divide by 100. However, it's the reverse when converting 1/cm to 1/m. You need to multiply by 100. 100 cm = 1 m.
Yes I got it. I'm a big fool. Thank you so much
Why did you use the equation with sin when the d is very small, I thought you use tan when d is very small 4:26
Love u
is there any difference between slits/m and lines/m sir
nah slits is just the difference between the gap and the other border its the same thing
I need assistance doing a physic work.. someone please help
what if I need to calculate the order... how do I do that?
im a year late but.... you gotta rearrange the equation so m is the subject.
i.e. (d*sin(theta))/lambda (wavelength)
In q no. 3 m getting a diff. Answer for d
Dear sir
Thanks for your video like it
Could you give all formula on laser questions ruby he neon
Thanking you
What the hell is this like n=length/no of lines so how this n suddenly equals to 1/d ???? What's this ?can you please reply me because may be my concept is built wrong.
I did this and got 1.1x10^8 but my lines were 500 per mm and the order was second and the angle was 24.8 what did I do wrong
at 1:10, does "m" correspond to minimums or maximums? because m0 seems to be at the central maxima, however m1 and m2 seem to be minimas. Could someone please help me out.
By my understanding, M1 and m2 are maximas
If there are 15000 lines per in a grating find the grating element
2:26 anybody else hear the intro for Phineas and Ferb?
Why do you do you do x10-9 on wavelengths
Naomi Kumson cause The wavelength is (ie 540nm) and 1 nm= 10^-7m then 100nm=10^-9
@@melissafigueroa4218 *1 nm= 10^-9m *
first question, wavelength was 650 why did it become 650x10^-9 ? pls im so confused
the initial wavelength was in nm, u have to convert it into meters for calculation
Answer Abhi chahiye
My brain is on the verge of exploding, ughhh i don't understand
Same is the case with me... its been 1 year of your comment so now if you're understanding this shit please help me too....

Hey! Do u know the difference between diffraction and diffraction grating?
Thanks a lot, sir
