The sound pressure versus time of a sound emitted by a speaker with constant pitch is as shown. 8.4 0.2 Sound Pressure (arbitrary) -0-2 -0.4 0.008 0.010 0.020 Time (s) When a sound with a higher constant pitch is emitted, the of the plot decreases Drag answer here amplitude When a louder sound with the same pitch is emitted, the of the plot increases. Drag answer here frequency period wavelength intensity
