PHYSICS 7C Midterm: physics7C-fa2009-mt2-Moore-exam
Document Summary
A clear explanation of what you are doing also helps in getting partial credit if there is a mistake somewhere. When a numerical answer is called for, an accuracy of 5% is su cient. Please do not turn this sheet over until the proctor starts the exam. Show clearly which side is air, which side is glass, and both re ected and transmitted directions. If so, write an expression for which incident angles will lead to tir. In terms of the speed of light in vacuum c, what are the speeds on the two sides: consider a double-slit interference experiment using a source of wavelength = 1 cm. The target screen is 100 meters away from the two slits. (a) (10 points) assume as usual that the source generates a plane wave that reaches the two slits at the same time.
