Researchers use a speaker to produce a sound wave with a particular frequency and amplitude in a gas-filled tube.Which of the following changes could produce a sound wave with greater energy?A.Decrease the amplitude of the waveB.Increase the amplitude of the waveC.Decrease the length of the tubeD.Increase the length of the tube

Which of the following is proportional to the amplitude of the sound where the frequency remainsconstant?

The amplitude of a sound wave

Increasing the amplitude means you are increasing the _________ of a wave.

Question 59A musician plays the trumpet in a marching band.  The musician tunes the trumpet inside a room and then goes outside to play.  When outside, the trumpet sounds flat (plays a lower frequency).  Which of the following has occurred to account for the decrease in the frequency?A.The air outside is warmer than inside, which increased the speed of the sound waves.B.More energy is dissipated outside, which caused the sound waves to lose energy.C.The musician shortened the length of the trumpet, which decreased the wavelength of the sound waves.D.The air outside is cooler than inside, which decreased the speed of the sound waves.

State what happens to the amplitude and the wavelength of the wave if1. the loudness of the sound is increased at constant pitch,amplitude ...................................................................................................................wavelength ................................................................................................................
