Respuesta :

F = 1/t
F = 1/0.5
F = 2Hz

Answer is 2Hz

The rope vibrates every 0.5 s: it means that its period is

[tex] T=0.5 s [/tex]


The frequency of an oscillation is equal to the reciprocal of the period:

[tex] f=\frac{1}{T} [/tex]

Therefore, if we substitute T=0.5 s in the formula, we get:

[tex] f=\frac{1}{0.5 s}=2 Hz [/tex]
