Graphics, Figures & Tables ⇒ tikZ | Stretch Picture horizontally

[ghostanime2001]

With my 2 figures below:
How can I have the second figure the exact width as the 1st figure above? I have tried to stretch horizontally using \begin{tikzpicture}[x=6cm] but that widens it wayyyyyyy too much What can I do? thanks..

Code: Select all

\documentclass{article} 
\usepackage{amsmath}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw (0,1.1) -- (6,1.1) node[midway,above] {B}; %top
\draw (0,-1.1) -- (6,-1.1); %bottom
\draw (0,-1) cos (6,0); %top curve
\draw (0,1) cos (6,0); %bottom curve
\draw (6,1.1) -- (6,-1.1) node[midway,anchor=west] {\quad $n=1$ \quad $L=\dfrac{1}{4}\lambda_{1}$}; %right
\draw[fill=black] (6,0) circle (1.6pt); %circle
\end{tikzpicture} \par\medskip
\begin{tikzpicture}
\draw (0,1.1) -- (3,1.1) node[midway,above] {C}; %top
\draw (0,-1.1) -- (3,-1.1); %bottom
\draw (0,1) cos (1,0) sin (2,-1) cos (3,0); %top curve
\draw (0,-1) cos (1,0) sin (2,1) cos (3,0); %bottom curve
\draw (3,1.1) -- (3,-1.1) node[midway,anchor=west] {\quad $n=3$ \quad $L=\dfrac{3}{4}\lambda_{3}$}; %right
\draw[fill=black] (3,0) circle (1.6pt); %circle
\draw[fill=black] (3,0) circle (1.6pt); %circle
\end{tikzpicture}
\end{document}

Your approach with a new x unit goes in the right direction. But since the lower picture is only half as wide as the upper one, you only have to double the horizontal units. So, instead of 6cm choose 2cm and you've got what you want.

P.S.: Very good minimal example.

How can I make my diagram a postscript file so that I can use it like a image in a \includegraphics command and align it to the top of a question number?

Not necessary.
