Answer:
[tex]\lambda =6.32\ cm[/tex]
Explanation:
given,
number of cycle complete (f) = 116 cycles per minute
wavelength observed at 11 m in 1.5 m.
[tex]v = \dfrac{distance}{time}[/tex]
[tex]v = \dfrac{11}{1.5}[/tex]
v = 7.33 m/s
[tex]\lambda = \dfrac{v}{f}[/tex]
[tex]\lambda = \dfrac{7.33}{116}[/tex]
[tex]\lambda =0.0632\ m[/tex]
[tex]\lambda =6.32\ cm[/tex]
The wavelength of the wave is equal to [tex]\lambda =6.32\ cm[/tex]
