There is another tutorial file explaining some more features of HTML for you. This time, you will learn how to more strictly specify how your document displays, by controlling things like font, font size, text color, background color, and such. You will also learn how to display pictures in your HTML file.
This stuff gets fairly heavy, but much of it is optional. You don’t need it to make your HTML file display, but you may want it to make your file display exactly the way you like. On the other hand, you really should learn how to display pictures.
Find a web site that has something to do with the physics of waves. Write one or a few paragraphs about it, explaining what you like about it. (Yes, it has to be a page you like about the physics of waves. Or at least you must find something you like about the page.)
You don’t have to put this in an HTML file, but it would be super-nice if you did. If you do, please include in your description:
Here are some other good HTML practices you should always follow:
Answer one, and only one, of the following questions.
These questions are for you to combine different ideas from the unit and apply them to situations not directly addressed in class or in the textbook. Think about the situation, and about the physics that applies to it. See me for help if you are stuck.
Does the longitudinal wave in a Slinky correspond to your idea of a “wave”? Why do we call it a wave?
When you added the two waves together in the 2-wave superposition applet, did any of the results surprise you? Which ones, and why? If there were no surprises for you, explain what a standing wave is and how standing waves are created in general—not just how the applet creates them.
The sound made by a metal bar when it is struck by another object depends on what the other object is and how and where the bar is struck. Why is that?
Water waves are complicated: they have both longitudinal and transverse characteristics, and their speeds depend on water depth and wave size. These properties play out to make water waves curl and break at the beach.
Where the water is deep and the depth is constant, an object floating on the surface of the water bobs up and down in a roughly circular motion as waves pass under it. At the shore, however, a floating object can ride a wave onto shore. Surfers exploit this fact for fun and profit. What is different about curling and breaking waves that makes this possible? Your answer should explain:
You may submit your entire response as a single HTML file. Or, you may submit the whole thing as hard copy or an electronic document. (However, I don’t recommend that because it will not give you practice with HTML.) Or, you may submit part 1 as an HTML file and part 2 as a hard copy or an electronic document.
If you submit any part of this assignment as an HTML file or an electronic document, upload it (or them) to Sakai using the “Assignments” tool. That way I will be able to find them easily and I will not tend to lose them.
