## Correlating 1st and 2nd editions of the text

This section is an attempt to point out major differences between the two editions of the text. Note that the Suggested Exercises and Problems for Practice for the 2nd edition of the text appear in pdf of the PowerPoint in which they were suggested.

### Chapter 20

#### Section 20.1

Figure 20.2 from the 1st edition has been dropped in the 2nd edition

#### Sections 20.2 - 20.5, 20.7

Largely unchanged

#### Section 20.6

The 2nd edition has added a discussion of decibels.

#### Suggested Exercises and Problems for Practice

1st edition: 1, 25, 35, 39, 53, 69, 71, 79, 82

### Chapter 21

This Chapter is largely identical in the two editions, except that in the 2nd edition Figure 21.14 has been expanded.

#### Suggested Exercises and Problems for Practice

1st edition: 7, 19, 25, 31, 49, 65, 71, 83 (skip part b, just use the result)

### Chapter 22

These are largely identical with one exception. The 2nd edition has a sub-section of Section 22.6 dealing with the Michelson Interferometer; this discussion is missing from the 1st edition. We will be discussing this interferometer not only as part of the Waves section of the course but also in the Relativity section. Thus, I urge you to read about this device in the 2nd edition.

#### Suggested Exercises and Problems for Practice

Problems 3 and 29 from the 2nd edition do not appear in the 1st edition. Problems that do appear in the 1st edition are: 5, 34, 71

### Chapter 23

#### Section 23.1

The discussion of magnification is dropped.

#### Section 23.4

The "derivation" of Snell's Law, which we sketched in in class, does not appear in the 1st edition

#### Section 23.5

What the 1st edition calls magnification M is called the lateral magnification m in the 2nd edition.

#### Section 23.8 - The Resolution of Optical Instruments

This Section in the 1st edition has been moved to Chapter 24 in the 2nd edition.

#### Section 23.8 - Image Formation with Spherical Mirrors

This Section in the 2nd edition does not exist in the 1st edition.

#### Suggested Exercises and Problems for Practice
