1. A note has a wavelength of 0.77955 m. If the speed of sound is 343.00 m/s, what pitch is this note?

The pitch depends on the value of frequency. The frequency can be calculated using this formula:

Frequency = wave speed / wavelength

where wave speed = 343.00 m/s

wavelength = 0.77955 m

Frequency = 343.00 m/s / 0.77955 m

= 434.00 s^-1

Therefore the pitch is low since the frequency is also low.
