Express the frequency in inverse seconds. n=5-->n=1
Natalija [7]

The frequencies expressed in inverse seconds are 5 s⁻¹  and 1 s⁻¹.

<h3>What is frequency?</h3>

Frequency is the number of complete cycles in a second made by a wave.

F = 1/T

F = n/t

<h3>When n = 5</h3>

F = 5/s =  5 s⁻¹ = 5Hz

<h3>When n = 1</h3>

F = 1/s =  1 s⁻¹ = 1Hz
