OCR Physics Unit 2 - G482 - (June Exams Preparation) Watch
I was stuck for ages then used Q=It and it gave the right value, not sure if it was the right think to do?
yeah i got 3600 and 720 too.
What did everyone put for the receiver R thing when it's moved by 0.75 cm?
I remember saying that they have an odd number of wavelength (quarter of wavelength) and so destructive interference etc etc..
did everyone write that?
the wavelength was 3 cm though, so i thought 0.75cm was a quarter of it!! aaahhh am i wrong? how did you get half?
This Paper was soo hard that i even botched the simple answers up like the show that questions -_-
