### The Physics Philes, lesson 99: I Have a Need. A Need for Wave Speed!

Over the past several weeks we’ve been learning about mechanical waves in all they’re wavy wonder. Today we’ll look a little more in depth at one key property of a wave: the wave speed. We’ll start off easy with the propagation of a transverse wave on a string. Don’t worry …

### The Physics Philes, lesson 98: The Most Important Equation in All of Physics

After a week hiatus for finals, I’m back with more physic-y goodness. Now…let’s see. Where did we leave off? Ah, here we go. It’s time to talk about particle velocity and acceleration, and, in doing so, we’ll find one of the most important equations in physics. So let’s get started. …

### The Physics Philes, lesson 96: Surf the Wave Function

After a brief break, I’m back this week with more about mechanical waves. For the next couple of weeks I’ll attempt to explain something called a wave function and how we can use it to understand a lot of the attributes of waves. A wave function is a mathematical function …

### The Physics Philes, lesson 94: Sinusoidal Infection

Last week we started talking about mechanical waves. Now that we have some of the essential knowledge under our belts, let’s dig in a little deeper. It’s time to start talking about periodic waves. A note: Everything you’re about to read goes for both transverse and longitudinal waves. But it’s …

### The Physics Philes, lesson 93: Do the Wave

We’re chugging along in our journey through introductory physics. We’ve made it through a discussion of fluid mechanics. Now it’s time to start learning about mechanical waves. Before we dive in, we need to nail down the basics. A wave is a fairly familiar thing. Most of us have seen …
