**First printing (2013)**

**Corrections to print version only; the
e-version is correct.**

**Page 113**. "1/*e*" should be "1/*e*^{2}"
in the Gaussian curve Figure 2.16, and insert "2" in the Gaussian equation
before "(*r/w*)^{2}" in Eq. (2.37). Interchange "1/*e*"
and "1/*e*^{2}" in line below equation (2.37)

**Corrections to print and e-version, before February
2015**

**Page 106**, line 2, sentence starting with "The
fastest..." should be "The slowest propagation corresponds to the highest
order mode (in the presence of many modes) with a group velocity, very roughly,
(*c/n*_{1})sin(theta_{c})."
Sentence right below Eq. (2.2.2) is not necessary (delete). See
Student Supplement^{Click},
which derives Equation (2.2.2)** | Page 116**, line below Eq. (2.3.2). Interchange
"(lowest mode)" and "(highest mode)". |
**Page 147**, Table 2.6, the units of *A*_{R}
should be dB km^{-1}
micrometer^{4}. (Units in Example 2.9.2 are correct.) **
|** **Page243**, Equation
(3.13.8), "633" should be "683" **
|**
**Page245**, Example 3.14.2, "633" should be "683" throughout; 0.63 lm should
be "0.68" and "2.8" should be "3.0" lm.

**New corrections to print and e-version after
February 2015 (to be corrected in 2nd printing)**

**Page 77**, Fig. 1.46 caption. Phi has 2pi
missing **|**
**Page 92**, Question 1.46, delete parentheses
in the denominator.
