# Speed of Waves

Before Class Preparation:

In Class Activity:

• Investigate the relationship between the wavelength, frequency, and speed of a wave, and solve related problems
• Group Work:
•  Speed of waves

After Class Work:

• Videos:

# Period & Frequency

Before Class Preparation:

• Make sure at least one person in your group has a metronome app
• Print (or BYOD) & Read this worksheet

In Class Activity:

• Metronome activity
• Graphing period vs frequency to determine the relationship
• Use spring to determine if period/frequency would affect the speed of a wave

After Class Work:

• Check Google Classroom for CK12
• A tutorial of mechanical waves here

# Introduction to Waves with Pendulums

Before Class Preparation:
