5. a b note has a frequency of 493.88 hz. calculate its wavelength in meters.

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.
