Question

When a tuning fork is struck, it produces sound waves of wavelength 114 cm which travel at 343 m/s through air. What is the frequency of the tuning fork?Choose one answer.a. 300 Hz b. 392.16 Hz c. 3.33 x 10⁻³ Hz d. 3.01 Hz

Answer 1

a. 300 Hz

Step-by-step explanation:

lamda = 114 cm = 1.14 m

v = 343 m/s

f = ?

v = f*lamda

f = v/landa

= 343/1.14

= 300/8

= 300.877 Hz

Answer 2

The frecuency is 300.88 Hz

Step-by-step explanation:

the frequency formula equals:

f = v/λ

where v is the velocity = 343 m/s and λ is the wavelenght = 114 cm = 1.14 m

Replacing values:

f = 343/1.14 = 300.88 Hz
