Question

two identical wires are under the same tension have a fundamental frequency of 500Hz . what fractional increases in the tension of one wire will give 5 beats per second. ?​

Answer 1

Answer:

We want one of the wires to alter the frequency by 6 Hz  = 0.01 or 1%

   frequency f = √[ T /μ ]

relative errors:    Δf/f = 1/2 *  ΔT/T  + 1/2 * Δμ /μ

Δf / f = 0.01   =>   ΔT/T = 0.02       as  μ = constant.

The fractional increase 0.02 or  2%

HOLA MATE

ANSWER:-

alter the frequency of one wire. by 6 Hz = 0.01 or 1%

frequency f = √[ T /μ ]

relative errors: Δf/f = 1/2 * ΔT/T + 1/2 * Δμ /μ

Δf / f = 0.01 => ΔT/T = 0.02 as μ = constant.

The fractional increase 0.02 or 2%
