Holstein–Herring method
The Holstein-Herring method is a way of calculating the electric field that is produced by an oscillating electric charge. It is named after its inventors, who were scientists, just like your teacher!
Think of the electric field as the way in which electricity moves through the air. Imagine you have a toy car that you want to push across a table. The harder you push, the faster the car will go. The same thing happens with electricity - the stronger the electric field, the more electricity will move.
Now imagine that the toy car is a tiny electric charge, like a little spark. If you move the spark back and forth very quickly, you will create an oscillating electric charge. The Holstein-Herring method allows us to calculate the electric field that this charge produces.
To do this, we first need to look at the charge from all possible directions. Imagine a little person on a hill looking out in all directions to see what the weather is like. That's what we're doing here - looking at the electric charge from all angles.
Next, we use a math trick called an integral to add up all of these different views of the electric charge. This gives us the total electric field that the charge produces.
This may seem complicated, but it's a really important tool in understanding how electricity works. So keep studying and you'll be able to use the Holstein-Herring method to solve all sorts of tricky problems!
