Physics 1C Lecture 25A "Somehow light is particle and wave. The experimenter makes the choice. You get what you interrogate for. And you want to know if I'm a wave or a particle." --Tom Stoppard

Quiz 2 Info It will be on Friday It is a Scantron test that covers Chapters 13, 14 and 24. A list of equations, constants, and conversions are available on the website and will be provided on the quiz. You are to write the version of your test on the Scantron form. Get it right to get credit. You will use the Quiz Code Number that you were assigned at the first Quiz. You are expected to abide by UC Policy on Integrity of Scholarship.

The Nature of Light The incident light ray will move in a straight line path as long as the medium does not change. But, when it encounters a boundary with a second medium, (at least) part of this incident ray is reflected back into the first medium. If the boundary is a smooth surface, the reflection is known as specular reflection . This means all the reflected rays will be parallel to one another.

The Nature of Light Although diffuse reflection is more common, it is harder to mathematically model than specular reflection. If the boundary is a rough surface, the reflection is known as diffuse reflection . This means that the reflected rays will travel in a variety of directions. Diffuse reflection is how you can see most everyday objects.

The reflected angle, θ 1 , is the angle that the reflected ray makes with respect to the normal. We define a normal (perpendicular line to the surface) at the point where the incident ray hits strikes the surface. The incident angle, θ 1 , is the angle that the incident ray makes with respect to the normal. 1 1 '
