# Quiz – Standing/Sound Waves

### Before Class Preparation:

• Finish Assigned Braingenies & Self Quizzes

### In Class Work:

• 15 minute group discussion
• 30 minute quiz: Application of Standing/Sound Waves

Can you:

• Determine a wave’s period & frequency when given a graph of the wave.
• Calculate the frequency of a standing wave in a medium that is:
• Open at both ends
• Closed at both ends
• Open at one end
• Calculate the speed of sound from a standing wave patterns in an air column closed at one end.
• Draw a standing wave pattern for an air column or string instrument and
• Calculate frequencies/lengths of the instrument
• Describe and calculate how sound changes (frequency, wavelength, velocity) through different mediums
