## Minds On Physics Internet Modules

Objectives - Waves

The Minds On Physics program consists of 16 modules - each covering a separate topic. Each module consists of a varying number of sublevels. Every sublevel addresses one or two objectives. The objectives for the Waves module are listed below.

### Waves - Objectives

• Sublevel 1:
• The student should be able to describe the nature of a wave and explain the distinction between wave motion and particle motion.
• The student should be able to identify and distinguish between contrasting types of waves.

• Sublevel 2:
• The student should be able to describe the basic characteristics of waves such as frequency, wavelength, amplitude, period, and speed.
• The student should be able to utilize mathematical relationships related to wave characteristics.

• Sublevel 3:
• The student should be able to define wave speed and identify the variables which effect wave speed.
• The student should be able to utilze the definition of wave speed to solve simple computational problems involving speed, distance and time.

• Sublevel 4:
• The student should be able to perform straight-forward calculations using the wave equation.
• The student should be able tointerpret textual information and diagrams in order to perform mmathematical analyses using the wave equation.

• Sublevel 5:
• The student should be able to predict how alterations in the medium through which a wave is traveling will effect the properties of that wave.
• The student should be able to predict the orientation of the reflected pulse at the boundary between two media.

• Sublevel 6:
• The student should be able to recognize the distinction between constructive and destructive interference.
• The student should be able to utilize the principle of superposition to predict the shape and amplitude of a wave form resulting from the interference of two waves.

• Sublevel 7:
• The student should be able to identify key concepts regarding the anatomy of a standing wave.
• The student should be able to relate the length of a medium to the wavelength of a standing wave established in that medium.

• Sublevel 8:
• The student should be able to mathematically analyze standing wave patterns.
• The student should be able to utilize a combination of textual information and diagrams to mathematically analyze standing wave patterns.
