What are Waves?

This week in class, we were introduced to a new topic. We started to talk about waves and what they are exactly. Well basically a wave is a disturbance or oscillation (vibrating) that travels through a medium from one location to another. A medium is defined as material that carries the wave. There are various types of mediums in the universe. Another thing we discussed is the two different types of waves. Transverse waves and longitudinal waves. Transverse waves have energy that moves perpendicular to the wave motion, while on the other hand longitudinal waves contains energy that moves parallel to the wave motion. Some examples of a transverse wave include, ripples on a pond or an actual WAVE in a stadium or sporting event. An example of a longitudinal wave is like a sound wave. Below I have included a video of my brother singing

This would be an example of a longitudinal wave because he is creating sound waves. Although we are unable to actually visually see the sound waves we are able to hear them. These waves are created by the oscillation or the vibrating of Duke's voice. His vocal chords vibrate to create this noise that we hear that is considered a longitudinal wave because the energy is traveling parallel to wave motion.
