UL4110 – Worksheets (particularly, refraction!)

September 14, 2015

Hi folks,

After our discussion today, I went back and reexamined the section on refraction. The confusion was my fault, as we’re using the concepts for light in the notes but we need to further develop the concepts for use with sound… using the index of refraction for light doesn’t work for us, and caused understandable confusion when comparing what we know about the speed of sound and densities of substances! At any rate, we’ll start tomorrow’s class addressing this and looking at the additional information provided on worksheet 4.

Worksheets are complete up to the start of Unit 3, which we’ll take a look at tomorrow as well.

Thanks for your patience!
