Notes: Sound Waves (PS.6b)

You will use the slides in this Quizizz lesson to complete your sound waves notes sheet.

You have as much time as you need to complete notes.

After each notes slide, you will answer a question to check your understanding.

Sound Waves

Multiple Select

Select all the statements that are true for a sound wave.

• is a mechanical wave

• is a transverse wave

• is a longitudinal wave

• requires a medium

Multiple Choice

Sound waves generally travel fastest through

• a solid because the particles are packed close together

• a liquid because the particles flow

• a gas because the particles have high energy

Multiple Choice

How does the temperature of the medium affect the speed of a sound wave?

• The speed of sound increases with the increase in temperature of the medium.
• The speed of sound increases with the decrease in temperature of the medium.
• The temperature of the medium has no effect on the speed of sound.

Multiple Choice

How are pitch and frequency related?

• high frequency = low pitch

• high frequency = high pitch

Multiple Select

Select all the statement that are true for a sound wave with a large amplitude.

• less energy

• greater energy

• louder

• quieter

Multiple Choice

This wave interaction or behavior allows instruments to produce louder sounds at certain frequencies.

• constructive interference

• diffraction

• reflection

• resonance

Multiple Select

Analyze the data table and select the TWO true statements.

• The sound waves traveled the fastest through copper.​

• The sound waves traveled the fastest through steel.​

• The sound waves traveled the slowest through the helium.

• The sound waves traveled the slowest through air.

Poll

Can you explain how the guitar uses resonance and strings to make the sounds we hear?

• Yes, I can write an excellent explanation!

• Not sure, but I try.

• No, I need help.

Research and Brainstorm

Use the links on the next two slides to complete your research (Iowa State University) and brainstorm (Science Buddies).
The links will open in a new table, and you will be able to keep the Quizizz lesson open until the end.
