Answer:
Time take to fill the standing wave to the entire length of the string is 1.3 sec.
Explanation:
Given :
The length of the one end
, frequency of the wave
= 2.3 Hz, wavelength of the wave λ = 1 m.
Standing wave is the example of the transverse wave, standing wave doesn't transfer energy in a medium.
We know,
∴ λ
Where speed of the standing wave.
also, ∴
where time take to fill entire length of the string.
Compare above both equation,
⇒
sec
Therefore, the time taken to fill entire length 0f the string is 1.3 sec.
