Calculate the wave length for several examples of sinusoidal electromagnetic radiation: radio, $1000 \mathrm{kHz}, \lambda=?$ television, $100 \mathrm{MHz}, \lambda=?$ red light, $4.3 \times 10^{14} \mathrm{Hz}, \lambda=?$ blue light, $7.5 \times 10^{14} \mathrm{Hz}, \lambda=?$ (Note for comparison that an atomic diameter is about $1 \times \left.10^{-10} \mathrm{m} .\right)$

Refer to a die that is loaded so that the numbers 2, 4 and 6 are equally likely to appear and 1, 3, and 5 are equally likely to appear, but 1 is three times as likely as 2 is to appear. One die is rolled. Assign probability to the outcomes that accurately model the likelihood of the various numbers to appear.

In Following the Equator, Mark Twain wrote, "Constellations have always been troublesome things to name. If you give one of them a fanciful name, it will always refuse to live up to it; it will always persist in not resembling the thing it has been named for." Choose a constellation that you have tried to observe or have seen on a star map. Draw the stars and connect them in a new way. Give the constellation a new name, and explain how you arrived at the name.
