Empty line on a slide in Latex Beamer

Question

I am using Latex Beamer for creating a presentation.

On one slide I have

\frame
{
  \frametitle{fdjsljklfdjs}
  What is fdjsljklfdjs
  \begin{itemize}
  \item item one
  \item item one
  \end{itemize}

  Why do we want to know it
  \begin{itemize}
  \item item one
  \item item one
  \item item three
  \end{itemize}
}

I would like to have space between the first itemize block and the second question. However, if I try \\ or \newline, I get a pdflatex parsing error:

! LaTeX Error: There's no line here to end.

How can I get an emtpy line?

Answer 1

Use \vspace, e.g.

\vspace{1in}

for a one inch vertical space. If you want it to be equal to the normal distance between two lines, use the length \baselineskip.
