Understanding Waves with Slinkies

What type of wave involves particles moving up and down?

• Pressure wave

• Sound wave

• Transverse wave

• Longitudinal wave

In a longitudinal wave, what causes the sound we hear?

• Magnetic fields

• Light waves

• Particles moving in circles

• High-pressure pushes and low-pressure pulls

How does the size of a vibration affect the sound we hear?

• It alters the sound's direction

• It modifies the sound's color

• It changes the pitch

• It affects the volume

What is the range of frequencies that humans can typically hear?

• 20 to 20,000 Hertz

• 30 to 30,000 Hertz

• 40 to 40,000 Hertz

• 10 to 10,000 Hertz

What results in a higher pitch in sound waves?

• More frequent pushes and pulls

• Less frequent pushes and pulls

• Larger wave size

• Smaller wave size
