OCR Physics Unit 2 - G482 - (June Exams Preparation) Watch
There were 2 questions that really threw me: The Electric Meter for the LDR and using the Double slit instead of two identical light sources. Took me a while to think those through.
For the wave question with WXYZ I put W at max speed, X at rest and W and X for the phase difference of 90 degrees.
Could someone enlighten me as to what happens to the speed of W oscillating when the frequency is doubled?
Obviously I'm not sure, but I do think it'll be around 63-65 for an A, which it has been before.
I used that first but then changed my answer Bit confusing of them to give two different EMFs! Hopefully won't lose more than 1 mark for that :/ Thanks
what did people get for the kwh question and how much it cost?
