OCR Physics Unit 2 - G482 - (June Exams Preparation) Watch
GOD I screwed up! I'm absolutely broken down right now! (someone cheer me up!) that paper was suppose to be 'relatively easy!' yet I ran out of time! grrrr!
Also, for the last question I put infrared first, with UV second.
What did the graph you had to draw look like?
Mine had a period of 0.2s, and I draw 2 full waves, 0-0.2, 0.2-0.4. Also has 0.010, 0.020, 0.030 on the sides (and the negatives of these values on the y-axis)
EDIT: It's only Edexcel. Learn to read James.
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?
