Today's class! =)

In today's class, we went over the waves in two dimension test. After that we corrected the four questions that were assigned yesterday.

We also got our lab back.

Then we watched a video about the waves and sound. It turns out that everybody have different sound waves when they talk. The video also showed some of the things that we already learned, like wavelengths, amplitude, transverse waves and etc. It also talked about the sound waves of the tuning fork and how the waves can cancel each other if you use two tuning forks with the same frequency and pitch.

And yes, we do have homework!

Well, that's all we did today! By the way, the answers are posted on the blog =)

Joseph is blogging tomorrow!! =P
