New unit info

According to Mrs. Frank this will be a quite easy unit. "Easy" is a relative term so we will see how that turns out. Very quickly we have gotten into a couple sets of notes. All of the notes so far relate to waves. Luckily i took physics last year and some of this is relate-able. The idea of a wave is a set amount of energy is put outwards through a medium. Traveling infinitely in a perfect system. The most common wave we experience is the light wave. Other waves we encounter are radio and microwaves, and ultraviolet rays give us a tan. Most of the information we have learned thus far is pretty straight forward.
