Hi Mr Lovatt! I'm Dang from Y10 in BIS. You've taught me physics a while back. I'm in college rn study about computers but I'm still heading back here to learn Physics for a bit of fun ^^. I'm glad to be able to revisit these wonderful videos. Hope you are doing well & you'll continue to make these videos for your future students. (P.S This is the video that actually saved me my IB Higher Level physics during my year 13 so thank you for that xD)
Thank you for your kindness to explain all the rules. I really appreciate. I have a question about your drawing at 7:30. Do we have to follow another rule as "one coming in, one coming out at each vertex"? Then, to follow the rule, should we rearrange the positron arrow downward and the photon is vertically upward, indicating that the photon is the product after the interaction?
