Sound travels at about 360 meters/sec. What is the wavelength of sound with a requency of 720Hz?​

0.5 m

Explanation:

Given:

Wave velocity ( v ) = 360 m / sec

Frequency ( f ) = 720 Hz

We have to calculate wavelength ( λ ):

We know:

v = λ / t [ f = 1 / t ]

v = λ f

= > λ = v / f

Putting values here we get:

= > λ = 360 / 720 m

= > λ = 36 / 72 m

= > λ = 0.5 m

Hence, wavelength of sound is 0.5 m.
