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.

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
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 .

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 :p

And any past paper that had waves?

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 .

Thanks for this! (Y)

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

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
