How is amplitude related to wave speed?

• They are directly related. If wave speed increases, so does amplitude

• They are inversely related. If wave speed increases, amplitude decreases

• There is no relationship. Amplitude and wave speed are not dependent on each other.

With sound waves, amplitude is measured by

• pitch

• loudness/volume

• wavelength

• wave speed

the time it takes for one complete wave cycle is called the ________

• wavelength

• period

• frequency

• wave speed

You get stuck at a train stop. A train sounds its horn as it drives by you. How will the pitch change as the train moves away from you?

• the train horn will not change in pitch as it moves away from you

• the train horn will sound higher in pitch as it moves away from you

• the train horn will increase in pitch as it moves away from you

• the train horn will sound lower in pitch as it moves away from you

How is pitch related to frequency?

• the higher the pitch, the higher the frequency of the sound wave

• the lower the pitch, the higher the frequency of the sound wave

• they are not related

• the higher the pitch, the louder the sound

Two girls shout in the bathroom together. One has a deeper voice than the other. What is true about the speed of the sound waves they produce?

• the girl with the higher pitched voice will produce faster sound waves

• the girl with the lower pitched voice will have faster sound waves

• the girl with the lower pitched voice will have slower sound waves

• the speed of the waves will be equal since the medium is the same
