Question

Pls help i begg youuuuu

Answer 1

Pitch is the sensation of certain frequencies to the ear. High frequency = high pitch, low frequency = low pitch. 

f = c(speed of the wave) /  λ (wavelength)

1. 343m/s / 0.77955m = 439.99 Hz   
     This corresponds to pitch A 

2. 343m/s / 0.52028m = 659.26 Hz
     This corresponds to pitch E 

3. 343m/s / 0.65552m = 523.349 Hz
    This corresponds to pitch C

4. using f = c /  λ
  λ = c / f
     = 343m/s / 587.33 = 0.583999 m = 0.584 m
