Orders of magnitude (frequency)
Orders of magnitude refer to how big or small a number is compared to other numbers. To help you understand this, let's pretend that you have a bag filled with marbles. There are different ways to categorize those marbles based on how many you have.
First, you could group them by ones, which means you count them one by one. If you have 5 marbles, you count up to 5.
Next, you could group them by tens. If you have 50 marbles instead, you count them by tens, making 5 groups of 10.
You could also group them by hundreds. If you have 500, you would count 5 groups of 100.
Now, imagine you have 10,000 marbles. Instead of counting all of them, you could group them by thousands. This means you have 10 groups of 1,000 marbles each, which is much easier to grasp than counting all the way up to 10,000.
Using orders of magnitude is useful when we need to talk about really big or really small numbers, especially in science and technology. For example, the frequency at which a wave oscillates is measured in Hertz (Hz). However, sometimes the values can be really high or really low, so we use orders of magnitude to simplify them.
If we have a wave that oscillates at 10 Hz, we could say it has 1 order of magnitude. If we have a wave that oscillates at 100 Hz, we could say it has 2 orders of magnitude. If we have a wave that oscillates at 1000 Hz, we could say it has 3 orders of magnitude, and so on. On the other hand, a wave that oscillates at 0.1 Hz could be said to have -1 order of magnitude, and a wave that oscillates at 0.01 Hz could be said to have -2 orders of magnitude.
In summary, orders of magnitude is a way to group numbers that are either really big or really small so that we can understand them easier. It allows us to simplify large numbers by looking at their approximations compared to other quantities.
