Properties of Waves

Hippocampus movie clip on ocean waves

Part 1:  Read the handout "Properties of Waves".  As you read make a list of the properties of waves.  Write a sentence that describes each property.

Resources:

Video clip (2 minutes) on wave properties

Part 2:  calculating waves' speed, frequency, or wavelength.

Using the formula provided, solve the following problems:

Speed = wavelength X frequency

Frequency = speed ÷ wavelength

Wavelength = speed ÷ frequency

1.  A wave has a wavelength of 5mm and a frequency of 2 Hz.  At what speed does the wave travel?

2.  The speed of a wave on a guitar string is 100 m/s and the frequency is 1,000 Hz.  What is the wavelength of the wave?

Part 3:  Waves on a String .  Explore the following web activity.  Write a summary of your findings, in particular address how changing amplitude affects frequency and wavelength and how changing frequency affects amplitude and wavelength..
