We know, this learning guide focuses on waves. But think of simple harmonic motion like the gentle training swells before tackling big wave surfing. Beach Boys’ music is still allowed."Simple har...
Wave Motion
All right, all right. So we've been holding back. You're here to learn about waves, after all. But simple harmonic motion is wave motion: the repeated oscillations of an object away from (and back...
