Physical Science 20 - Jan 14

Today we learned about standing waves and how they are formed.  These are waves that appear to be standing still and are caused by interference between an incident wave and a reflected wave.  The terms nodes and antinodes were introduced and we looked at some formulas that show the relationship between the distance between adjacent nodes and the wavelength, as well as the length of the medium and the wavelength.  Students were to work on Homework 5.4 from yesterday and have that done for tomorrow.
