Just wanted to put in my two cents on this one, given that I've looked into the topic before. What it really comes down to is the need of Materials Engineers and Scientists to compare values such as mass-density or line-density at the atomic scale. The lengths are generally large enough that we...

Shouldn't that be ##\lambda = \frac{2\pi}{k}## ?

Homework Statement This is Problem 7.6 from Electronic Properties of Engineering Materials by Livingston. "Over a wide range of frequencies, the dielectric constant of a polymer is found to be proportional to the inverse square root of frequency. (a) How does the phase velocity of EM-waves...
