Answer:

260 Hz

Explanation:

The frequency of a sound wave is  defined as the number of oscillation which is given in cycles per time. Frequency (f) is given  by the formula ;

[tex]f = \frac{1}{T}[/tex] and it is measured in Hertz(Hz)

Given that;

a vibration is caused by a struck string in piano at  260 cycles and Time (T) = 1 seconds

Frequency (f) can be determined as; 260 cycles × 1 seconds

= 260 Hertz (Hz)

Hence, the frequency of the sound wave is 260 Hertz (Hz).
