Question

The sound from a trumpet travels at 351 m/s in the frequency of the note is 294 Hz, what is the wavelength of the sound wave?

Answer 1

1.19m

Step-by-step 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 ∧

∧ =
`(351)/(294)` = 1.19m
