Arrangement for filtering monochromatic beam from incident white light is called interference filter.. When a narrow beam of white light is incident on the filter, it undergoes multiple reflections in the dielectric, it loses a major part of its intensity and finally emerges from the filter as a very narrow band with one or two maxima.. By- Dr P M Patel. Introduction:. Interference and diffraction phenomena proved that light is a wave motion. These phenomena are used to find wavelength of light and they do not give any indication regarding the character of waves.. Associate Professor in Physics. Post Graduate Govt. College Sector-11.

What is the difference between an enantiomer and a diastereomer?. Enantiomers and diastereomers are two types of stereoisomers. Enantiomers include mirror images and non-superimposable chiral centers. Diastereomers contain non-superimposable chiral centers, but are not mirror images. Depending on the number of stereocenters, there could be far more than 2 compounds.. result from the laws of reflection and refraction. .
