We commonly use meters to make measurements in electric circuits but meters are relatively simple devices and if the property we are measuring changes over a short period of time then a meter will not show this clearly (if at all). But a different instrument, the oscilloscope, has the power to reveal such changes in … Continue reading DC and AC Electricity Pt2: Seeing the Difference
Electron Shells
The idea of electron shells is essential in chemistry and also plays an important part in various areas of physics so needs to be discussed in its own right. But before we look at electron shells let's be clear that this is just a model - a way of imagining what is going on inside … Continue reading Electron Shells
Waves: note-taking task
One of the most important study skills is note-taking. Some students complain that they do too much writing so in the Waves topic we'll be trying out a different approach based on Cornell Notes. The method was covered in class but I've included a screen-grab here to remind you what it looks like - but … Continue reading Waves: note-taking task
