Answer:

1.19m

Explanation:

Given parameters:

Speed of the trumpet sound  = 351m/s

Frequency of the note = 294Hz

Unknown:

Wavelength of the sound  = ?

Solution:

To solve this problem, we use the wave - velocity equation.

    V  = F x ∧  

V is the velocity of the body

F is the frequency

∧ is the wavelength

 So;

          351   = 294 x ∧  

       ∧   = [tex]\frac{351}{294}[/tex]   = 1.19m
