Today's physics class was like any other day. Today however was a club period so we did not have enough time to talk about waves. We started off class with a Daily question which was A pulse in a higher density medium (like a slinky) is traveling towards a boundary with a lower density medium (like a string). We then answered this question with 3 answers. The first being the reflected pulse in the slinky will not be in inverted because it's an open end barrier. The second was the speed of the reflected pulse will be the same as the speed of the incident pulse. The third question was 'if the speed of the wave was 5 m/s with a wavelength of 2 m what is the speed. We solved this to get an answer of 4 m/s. After the daily question, we took notes on the transmission of waves. To help us get a better understanding of this we watched some more wave videos like yesterday. Then after this mr manning taught us abut notes on interference while giving demonstrations with the slinky as pictured below.
