Ответ:
Speed of the wave in the string will be 3.2 m/sec
Explanation:
We have given frequency in the string fixed at both ends is 80 Hz
Distance between adjacent antipodes is 20 cm
We know that distance between two adjacent anti nodes is equal to half of the wavelength
So![\frac{\lambda }{2}=20cm](/tpl/images/0582/0727/edf87.png)
We have to find the speed of the wave in the string
Speed is equal to![v=\lambda f=0.04\times 80=3.2m/sec](/tpl/images/0582/0727/38211.png)
So speed of the wave in the string will be 3.2 m/sec
