A lesson on X-rays, and how they are produced. Covered at the depth required for high school Physics. For students of NSW, this cover the dot points in the Medical Physics elective (9.6) •describe how X-rays are currently produced • compare the differences between ‘soft’ and ‘hard’ X Rays
In this video, I discuss Positron Emission Tomography. In particular, I refer to the source of the positron, its annihilation and how the resultant gamma rays are collected. I also briefly discuss its diagnostic benefits.
In this video, I explain simultaneity using a question from the 2011 HSC physics paper
An explanation of band theory, discussing the difference between conductors, semiconductors and insulators, including a useful analogy.
An explanation of intrinsic semiconductors work, in light of Band Theory.
The third in the series on semiconductors, this video explains how doping a semiconductor such as silicon, improves its conductive properties, using band theory model to explain. This video aligns with the NSW HSC syllabus but is applicable to other jurisdictions.
A quick explanation of the doppler effect using an animation written by W. Christian at Davidson College. This useful animation to undertaking pitch change in moving sound sources and also how ultrasound (sonograms) can measure blood flow.
In this video I teach you to use the acronym of RUDE to help you solve physics calculation problems and a logical and sequential way
Here are my top ten tips in doing exams. Although the focus is Physics, and science in general, you can apply them in any subject.
