When I speak in a high-pitch voice, the sound waves have

• high amplitude

• low amplitude

• high frequency

• low frequency

When I speak with low energy, the sound waves have

• low frequency

• low amplitude

• short wavelength

• high amplitude

Frequency and Wavelength have inverse (opposite) relationships!

• True

• False

Waves with a low frequency must have

• low amplitude

• long wavelength

• short wavelength

• low energy

To decrease the amplitude, I should

• draw shorter waves

• draw "smaller" waves

• draw less waves

• draw waves with a longer wavelength

To increase the frequency, I should

• draw taller waves

• draw waves with a longer wavelength

• draw waves with more energy

• draw more waves

Frequency is related to the volume and the amount of energy in a sound wave.

• True

• False

A sound wave has a long wavelength. This wave has

• loud volume

• high pitch

• low pitch

• soft volume
