Answer : Frequency,
$\\u=(1)/(8)\ Hz$

Explanation :

The equation of a particle executing SHM is given by :

$y=A\ sin\omega t$ .........(1)

Where,

y is the displacement

A is the amplitude of the wave

$\omega$ is the angular frequency of the wave

t is the time

The given equation is :

$y=5\ sin((\pi)/(4))\ t$ ............(2)

Comparing equation (1) and (2)

$\because\ \omega=2\pi\\u$

So,

$(\pi)/(4)=2\pi \\u$

$\\u=(1)/(8)\ Hz$

Hence, this is the required solution.
