My 1st day in class !!!!!!

Hey watz up blog and teacher. Right now I am in class. I learned many interesting things that I never would have thought of today. We learned about the wavelength of audio ,which is the length that a wave completes within a cycle. Frequency, which is the number of cycles a wave completes within a second. Velocity, which is how fast the sound moves. Amplitude, which is basically the peak volume of a wave. We also learned a couple other fascinating things about sound but I can't type so I won't go into all of it. Overall though the first day in class was pretty cool!!!! Blogout!!!!!!!!!
