Changing the amplitude of a sound waves changes...

(a)  

• How fast the sound travels

• The pitch of the sound

• The tone of the sound

• How loud the sound is

How is the energy of the wave affected if the amplitude of the wave increases from 2 meters to 4 meters?

(a)  

• It is quadrupled
• It is halved

• It remains the same

• It is doubled

If you press down on a piano key, let's say middle C, it generates a sound wave. Now, imagine that you press it down much harder so that it still plays the same tone but much more loudly. How would pressing the key down harder change the sound wave produced?

(a)  

• frequency would increase
• energy would decrease
• amplitude and energy would increase
• wavelength and energy would increase
