Has anyone done p5 question 1 of nov 12 paper 53

Finally found evidence that u can measure time periods sorry guys for giving two contradicting posts .

Look at the link and you will know once u have a light gate connected to a data logger u can get time interval between the object passing the light gate once and then again by finding time on data logger .
Yousif Mukkhtar heres your answer and you were right on page 9.

Yes i have

Heres what i got to know abt the light gates.
Light gates are connected to a data logger and when something passes in between the light detector and light source and blocks light reaching detector a timer in data logger starts and does not stop until light gate is no longer blocked. So u have the time for the object to pass through the light gate. Now u may use it to get speed only if its constant like terminal speed by dividing the length of the object divided by this time. I dont know how useful it is but thats all i can find.
For measuring periods i dont think its possible to do that with this.

Any past paper question regarding the use of Light gates?

Can you send the screenshot please, I can't understand what to write ive made the diagram though

Any past paper question regarding the use of Light gates?

The most difficult question in recent years that i found and it had light gates use but it was optional other ways were there.
M/J 12 /P53 Q1 ,P51 Q1 is also same so do any one .

yeah it was a toughy but only cause i got the independent variable wrong :/

Ive tried hard but i cant get my laptops webcam work i guess there is a problem with drivers and stuff since my bro updated the computer so i can just tell u what u need. Just copy the same diagram as given and add filters on to lamps or just replace the thing with lasers if u want to . Also show distances from observer to each lamp and also distance from observer to centre of the line joining the center of the lamps and also show a metre rule just to show u will use it to measure the distances.
The rest u need to write and explain and u cant show it here .

Any prediction looking at recent years what topic Q1 will be on tomorrow ??

well all i can say is it is proll gonna be on a untested topic . something new ridiculusly stupid :/

I think something on waves may come because it hasnt come for a long time. Long time back they gave a question on stationary waves i actually screwed up the experiment and started measuring time periods and started oscillating the bottle in which stationary wave was to be set up

And any past paper that had waves?

Thanks for this! (Y)

which year was this?

Thanks and what an awesome help you gave. Yeah, you know light gates are a wonderful invention Love it more than other devices

After drawing our error bars....how exactly do we find our best/worst fit line?? Do they somehow have a connection???

 

[LeQuavina]

guys how do we find the error of n. may/june/08 Q2) d)

 

[Igcse stuff]

Can someone explain or share some notes for diffraction grating, stationary waves, interference and youngs double slit for Paper 5...something similar to the above topics came in 2012 October november

 

[Igcse stuff]

Are there going to be major changes in physics p5?

Worst fit is a line connecting top side of error bar and bottom side of error bar

 

[Igcse stuff]

Can someone help explain diffraction grating, stationary waves, interference and youngs double slit for Paper 5 Q1....A similar topic came in 2012 October november
