Physical Science 20 - Nov 6

Today in class we learned about the next property of light, called the rectilinear propagation of light - this means that light travels in straight lines.  Students did the Activity called Lab 2.1 and most students handed it in by the end of the period.  This lab does not require a formal lab report; students just need to hand in the sheet the accompanied the activity. This will be due on Monday. Have a good weekend everyone!
