Question
You can use the pressure meter tool to keep track of the pressure at a particular place over time. Place the detectors Into the middle of your sound wave box. Hit play and then PAUSE and adjust the position of your pressure sensors. 7. Where particles are close together (In the light color bands). pressure is 8. Where particles are further apart (In the dark color bands), pressure is Hopefully you noticed that a high pressure reading matches a where the particles are close together in a light-coloured band. This is called an area of wave compresslon. Where particles are further apart in the dark coloured band, there Is less pressure. Scientists call these areas of the wave rarefactlons. • Set the amplitude to zero. This shows where the particles would be if there Is no sound. • Slowly Increase and decrease the amplitude. • Use the pressure tool to measure pressure. You may have to do this a few times to see a pattern. 9. Insert a screen capture of pressure waves that would Indicate a low and high amplitude. Low Amplitude Hıgh Amplitude 1 ms Time 1 ms Time 10. Which type of wave generates more pressure? Frequency Frequency • Select Play Tone and Particles on the settings panel. • Move the Amplitude slider to halfway. • Keep the Frequency slider at the halfway positlons too. • Press the green button on the speaker. Amplitude guit max O Graph & Play Tone O Waves O Particles O Both Move the Frequency slider up and down. 11. How does the sound change? 12. How does the motion of the particles change as you Increase the frequency of the sound waves? You can also draw a dlagram of what you observe. Pressure Pressure
