Question

1. the ____________ affects the pitch of a note.

a. amplitude
c. wavelength
c. frequency

1. the ____________ affects the volume of a note.

a. amplitude
b. crest
c. wavelength

1. the ____________ is the distance from one crest to the next.

a. diameter
b. wavelength
c. frequency

1. the high point of a wave is the ____________.

a. amplitude
b. crest
c. wavelength

1. which instrument has a higher frequency/pitch?

a. flute
b. tuba

Explanation:

1. Pitch of a sound note is determined by how often sound waves vibrate, which is frequency.
2. Volume (loudness) of a note depends on the height of sound wave peaks, which is amplitude.
3. The definition of wavelength is the distance between consecutive wave crests (or troughs).
4. The highest point of a wave is defined as its crest.
5. A flute produces higher, thinner sounds (higher frequency/pitch) compared to the low, deep sounds of a tuba.

Answer:

1. C. Frequency
2. A. Amplitude
3. B. Wavelength
4. B. Crest
5. A. Flute
