Module 6: Waves

A wide range of physical phenomena can be described in terms of waves. Waves are essential to our understanding of sound and light, and are used to explore topics from the motion of electrons to the origins of the universe.

In this module, you will learn some vocabulary associated with waves, then you will go on to explore various phenomena associated with waves.  You will see how these phenomena are observed in both sound and light. You will look beyond visible light to the other portions of the electromagnetic spectrum and see how essential waves are to your everyday activities.

Pre-Assessment:

Make some waves. Fill a sink, a bathtub or a large container part of the way with water. Using your hand, a utensil, or some other object, disturb the surface of the water. Now, using your hand, a utensil or some other object, disturb the surface of the water. First, make a single disturbance and record what you observe. Next, disturb the surface regularly and repeatedly and record what you observe. Change something about how you make the disturbances by changing the magnitude, the rate or some other factor. Record what you observe. How can you describe the different waves you create? How do the various waves differ? Do you notice any other interesting phenomena about the waves?

Post your observations on the discussion board. Make your initial post, then return to the discussion board several times over the next few days to read your classmates’ posts. Reply to at least two of them, being sure to offer new insights, ask questions, and encourage further conversation.
