Explanation Given data: λ = 39.1 cm , v air = 344 m s , μ = 0.600 g m and T s = 150 N . Formula used: Write the expression for velocity ( v ) v = λ f (1) Here, λ is the wavelength, and f is the frequency. Write the expression for wavelengths of standing wave ( λ m ) . λ m = 2 L m (2) Here, L is the length, and m is the mode number that is 1,2,3,4. Write the expression for wave speed on a stretched string ( v string ) v string = T s μ Here, T s is the tension, and μ is the linear density. Explanation: Modify and rearrange equation (1) to find frequency of the sound wave. f = v air λ Substitute 344 m s for v air and 39.1 cm for λ , f = ( 344 m s ) 39.1 cm = ( 344 m s ) 39.1 × 10 − 2 m { ∵ 1 cm = 1 × 10 − 2 m } = 879.79 Hz The frequency emitted by the wave on the string is same as the frequency of the sound wave. Modify and rearrange equation (1) f = 1 λ ( v string ) Substitute T s μ for v string , f = 1 λ ( T s μ ) Substitute 879

Seiche

A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water includ…
