I tried to insert a figure into an article with two column that I am writing, this is the relevant part of the code:
Code: Select all
\subsection[Interferometry based Spectral Instruments]{Interferometry based Spectral Instruments}
\subsubsection[Interference Filters and Fabry-Perot Interometer]{Interference Filters and Fabry-Perot Interometer}
\begin{figure}[ht]
\centering
\includegraphics[width=0.50\textwidth]{InterferenceFilter.PNG}
\caption{Generation of multiple rays in an interference filter and intensity distribution of transmitted light.}
\label{fig:InterferenceFilter}
\end{figure}
Path difference...
Why?
What can I do about it?
