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 =
By substituting the given values in the formula,
λ =
λ = 0.6945 m
Therefore, wavelength of the music note is 0.6945 m.
Option (1) will be the answer.
