Question

Use the information below to solve this problem: A B note has a frequency of 493.88 Hz. Calculate its wavelength in meters. Question 2 options: 0.6945 m 0.7204 m 1.439 m 343 m

Answer 1

Answer:

Option (1). 0.6945 m

Explanation:

Frequency of a B note = 493.88 Hz

Speed of sound in the air = 343 meters per second

Since, formula to calculate the wavelength of a note is,

λ = $\frac{v}{f}$

By substituting the given values in the formula,

λ = $\frac{343}{493.88}$

λ = 0.6945 m

Therefore, wavelength of the music note is 0.6945 m.

Option (1) will be the answer.
