A woman is deciding between three alarm systems to install in her home. Each alarm system produces a wave with a different wavelength and decibel level, as shown in the following table.

1st number: Wavelength (cm)

2nd number: Decibels (dB)

Alarm A

8

100

Alarm B

32

80

Alarm C

128

60

If the woman wants the alarm with the lowest pitch, which alarm should she choose? Explain your answer.
