Your videos always make me feel so confident because I understand it so much better and I can do it correctly. If only in the exam they asked the questions in a straightforward way then I could get full marks.
I have a number of vids on AS and A2 going thro typical exam questions. You can find them on my RUclips channel under the playlist "A Level Physics Exam Questions - Worked Examples"
This helped so much! I'm currently doing AS physics and Waves/Optics was the only bit I struggled with (so far)... I'm glad I found this, and will probably watch it once more before my actual exams come summertime
With some essay questions, however, how would you go about explaining the formation of a stationary (or I suppose, standing wave)? This would probably be a 6-mark question, and other than nodes and anti-nodes how would I answer this type of question?
Ah. I hadn't seen this when I answered your last question. I haven't tackled the essay questions because they are essentially answered in my main videos. It's really a case of making sure you cover the essential details. Hope it goes well.
I assume you mean a light wave moving from, say, water, to air. Some of the light is reflected back into the water and some is refracted out. Beyond the critical angle all the light is reflected (total internal reflection).
I've seen your exam questions videos but I wanted to see your approach to the exam questions like the odd ones out and how to do the 6 mark essay questions which I tend to lose marks on a lot.
+Abdullah Khaleel My complete playlist is intended to cover the syllabuses of AQA, CIE, OCR and Edexcel but obviously not all videos are relevant for each course.
Hi I know this might sound inconvienent but actually I wanted to ask you something. Basically my physics exam is on wednesday(Mechanics, Materials and Waves) and my exam board is AQA. I'm in my first year AS and I seem to be struggling with the exam questions now it would be awesome if you could make a video going thorugh an AQA recent exam paper like June 2012 and do questions with working out so I can understand it better, if you could so this by this weekend it will seriously help me a lot.:)
lilmayhem46 Thanks. I try to cover the material for AQA. OCR, Edexcel and CIE so there may be material in my vids which isn't covered in all the exam boards.
What is the meaning of A level, AS etc ? Because i have seen all your video about question example. And i think that too easy for me. Fyi i'm still eleventh grade

Thanks for kind words. I wish you well in any exams which might be coming up for you.

this video is absolutely brilliant! a good video for revision for exam! thank you! please continue to make more of these problem based videos!

Helped alot. Thanks. Would'nt have passed without this!
you r simply superb ..... oh my only wish is that our physics teacher was like you ... thank u for the videos
Tmr i will have my physics exam, and I just found your channel yesterday
Yes. I have done a vid on AS Electricity exam questions recently.
All good wishes for your exam. Hope the videos help a bit.

Thanks for this video :) really helped me to understand which equations I would use for certain types of questions!

Jack Daniels: You look up sine tables (or from your calculator) to find the angle whose sine is 0.317
No specific board. They are generic questions covering a range of Board questions.
11:20 could you answer that question by saying a stationary wave does not transfer energy while a progressive does ?
Thanks Dr , best video ever , i subscribed to your channel , that one about the black wholes was great!
thanks dr
Yes. But d is 1/4x10^5. So 1/d is 4x10^5. Is that the point you were making?
I've seen your exam questions videos but I wanted to see your approach to the exam questions like the odd ones out and how to do the 6 mark essay questions which I tend to lose marks on a lot.
Why is it that d=1/3.7x1-^5 ? What does the 1 represent and alos what does lines/m (lines per meter i know) mean? Thanks!
Thanks you, I am learning about this,it's good to know and learn more than the other students. Thanks again ,very helpful :)
Nice video, do have any videos that have exam questions for as level physics for circuits, dc circuits and resistance? Thanks :)
after finding the position ( n) why we add +1 to that n??
when does partial reflection occur? becasue in one past paper you got a mark for showing partial reflection but i not seen it in any other paper?
Thank you
does this video cover cambridge cie +DrPhysicsA

So, it’s been seven years, what you doing now?
At 3:29 how did you get 18.5?
He did the reciprocal of 0.137, Sin^-1(0137) = 18.5 deg.
Biscuits, Cheese Biscuits He did sin^-1(0.317) which equals to 18.5
This video is not updated !!!
The current syllabus is totally different.
Utkrist Shrestha Yeah I saw that too
wouldn't it be sin(theta) = (n * wavelength) / d, not sin(theta) = n * wavelength * d?
Can you tell me where in the video this arises please?
DrPhysicsA 19:48
dr chemistry A any time soon ? :D
check out E rintoul you wont regret it
What exam board are these questions derived from?
this is so different from the OCR spec I'm a little confused:s
Have you seen my main video on Waves (as opposed to the exam questions) at Waves - A Level Physics
DrPhysicsA
yes it was very helpful i watched it before watching this but I'd like to know what exam board you cover, or do you just cover everything?
lilmayhem46 Thanks. I try to cover the material for AQA. OCR, Edexcel and CIE so there may be material in my vids which isn't covered in all the exam boards.
absolute legend
dSin(Theta)=NWavelength is A2
not for aqa A right now im doing as level
no its in my as phy exam
What is the meaning of A level, AS etc ? Because i have seen all your video about question example. And i think that too easy for me.
Fyi i'm still eleventh grade
In UK, AS level (A1) is year 12 and A-level (A2) is year 13.
