3
the wavelength is the distance between two repeating points on a wave. often the crests, or highest points of waves, are used to measure wavelength.
a sound wave with a shorter wavelength has a higher pitch.
a sound wave with a longer wavelength has a lower pitch.
choose the correct answer.
which sound wave has the lowest pitch?
wave 3
wave 2
wave 1

Explanation:

• The key concept here is the relationship between wavelength and pitch in sound waves.
• As stated, a longer wavelength corresponds to a lower pitch.
• By visually comparing the waves, Wave 3 has the longest wavelength.

Answer:

Wave 3.
