How to progressively uncover a formula in Beamer?

In this tutorial, we will learn how to uncover a formula in Beamer using \onslide command. The following minimal working example highlights how to uncover the Schrödinger’s equation step-by-step:

% Uncover formula in Beamer
\documentclass{beamer}

% Theme choice
\usetheme{AnnArbor}

% for the mathematical part
\usepackage{amsmath, bm}

\begin{document}

\begin{frame}{Schrödinger’s time-dependent equation}

% Slide 1
\only<1>{\[ i\hbar \]}

% Slide 2
\only<2>
{
    \[ i\hbar \frac{\partial}{\partial t}{\Psi(\bm{r}, t)}\]
}

% Slide 3
\only<3>
{
    \[ i\hbar \frac{\partial}{\partial t}{\Psi(\bm{r}, t)}=\left[ \right] \Psi(\bm{r},t)\]
}

% Slide 4
\only<4>
{
    \[ i\hbar \frac{\partial}{\partial t}{\Psi(\bm{r}, t)}=\left[ \frac{-\hbar^2}{2\mu}\nabla^2\right] \Psi(\bm{r},t)\]
}

% Slide 5
\only<5>
{
    \[ i\hbar \frac{\partial}{\partial t}{\Psi(\bm{r}, t)}=\left[ \frac{-\hbar^2}{2\mu}\nabla^2+V(\bm{r},t)\right] \Psi(\bm{r},t)\]
}

\end{frame}

\end{document}

which yields the following result:
