PHYS 1112 - Introductory Physics II
Lesson 23 - Wave Optics I

Study Assignment:

Study: Chapter 24, Sections 24.1 - 24.4

Lesson notes:

In this this lesson we will begin our study of interference phenomena. The double-slit interference experiment by Young was the first solid experimental evidence that light acts as waves. No explanation that prescribes a particle nature to light can explain the results of the double-slit experiment.

Objectives

1. Understand the definition of coherence as applied to light.

2. Understand the definition of monochromatic light.

3. Understand the definitions of constructive and destructive interference.

4. Be able to predict the positions of maxima and minima in double-slit interference.

5. Know the condition necessary for change of phase on reflection.

6. Be able to predict the thicknesses of films required to produce maxima and minima by interference.

Vocabulary:

incoherent
path difference
Newton's rings
