Post #21 - Waves

Today in class we learned about waves, waves, and more waves. Waves are everywhere. Waves are present in sound, light, and at the beach. A wave is a wiggle in time and space. We learned a ton of concepts relative to waves such as wave length (measure of wave from identical points), period (time it takes a cycle to be completed), and frequency (the # of cycles that past in a second). The two types of waves we learned about were transverse waves (wave energy that moves perpendicular to the wave velocity) and longitudinal waves (wave energy that moves parallel to the wave velocity).
I encountered waves today when I went surfing. In the ocean the waves are transverse waves because its motion is perpendicular to the direction it travels in.
