The problem asks to solve for $f$ in terms of $T$ given the equation $T = \frac{1}{f}$.

1. Problem Description

The problem asks to solve for $f$ in terms of $T$ given the equation $T = \frac{1}{f}$.

2. Solution Steps

We are given the equation $T = \frac{1}{f}$.

To solve for $f$, we can multiply both sides of the equation by $f$:

$Tf = 1$

Now, divide both sides of the equation by $T$:

$f = \frac{1}{T}$

3. Final Answer

$\frac{1}{T}$
