Introduction:

Gowrie waterhole in the Kruger National Park, Republic of South Africa

You might think that jumping from Chapter 1 to Chapter 29 in a textbook would cause a lot of confusion because you don't know what was in the 27 chapters in between, but in this case, there isn't much of a problem. All you need to remember is:

If the text says...	You should read...
wave	ray
frequency or wavelength	color

For instance, if the text has a sentence that starts

"The frequency of the light wave..."

you should think

"The color of the light ray..."
