Why is there a time gap between lightning and thunder in an electrical storm?

Lightning is an electrical discharge from two areas with a large imbalance in charge. Thunder is a sonic shock wave that is caused by air being made to travel faster than the speed of sound. If you see lightning, then start to count it is possible to work out how far away the eye or […]

How do I learn the equations for the Electricity topic in GCSE or IGCSE Physics exams?

Are there any nice analogies of spin to explain it to A level physics students?

Diagram below has a really nice analogy of integer spin 1,2 and half spin 1/2. It’s a shame any A level physics syllabus ( to my knowledge) doesn’t really seem to explore Quantum numbers except the Principal Quantum number in any level of detail. Quantum physics almost always captures the imagination of 6th formers. Read […]
