 ABSTRACT

                           The object of present study was to study the ceramic Moon light scattering during days of volcanic ash dispersal over the sky in Visakhapatnam and compared with observations made earlier two days in Rayagada before the volcanic activity. The 13 and 14  February 2014 February observations made using a grating element on the terrace of MITS Engineering College, Rayagada, around 8 PM using grating element of 15000 lines of our college.
                        We define a new quantity named lortusity as the ratio of the real path length to the apparent path length in a ceramic material. Since the findings are based on the light intensity variations with coupled movement of intense Volcanic and other preliminary affects of it. The ‘connectivity‘ of pore space, viz., the number of pores meeting at a point, in a porous media by regular packing is predominant in graphite. 

Words: lortusity, connectivity.                      

INTRODUCTION AND  PRESENTATION

 Four ceramic slabs have been used viz., Graphite, Marble, White and Blue ceramic plates. The Moon light reflected from the slabs has been recorded for their spectral display.  The observations repeated again on 14 instance, and the spectra recorded using the Digi camera of 12 Mega Pixels.  In both the cases the author successful to obtain the spectra that provided a means to study the ceramic Moon light scattering. Afterwards when he came to Visakhapatnam on the 15 February, to repeat again the observations, he is fortunate have the effect of Volcano activity dispersion of the sky and the spectra recorded again.     

Listed below: Fig.1a. (only three from Rayagada), Fig.1b (four photographs from Rayagada) and Fig.2 (only two photographs from Visakhapatnam with volcano effect) given below project briefly, the spectra recordings made by the author, are of a unique character. 

FROM RAYAGADA

Fig1(a) spectrum 13 February, Graphite ceramic;

                   The molecules of the graphite are tightly bounded so the spectrum is quite distinct.

      

Fig.1(a) spectrum 13 February, White ceramic;

                   The molecules of the ceramics are bound softer than graphite so the spectrum obtained here is weaker than the spectra of graphite.

Fig.1(a) spectrum 13 February, Blue ceramic;

               The molecules are bound softer than white ceramic, so the spectrum obtained is more weaker than the spectrum of white ceramics.  The dominant colors are the Red and Green.

Fig 1(b) spectrum 14 February, Graphite ceramic;

              The molecules of the graphite are tightly bounded so the spectrum is quite distinct.             
                                      
                                   Fig 1(b) spectrum 14 February, Marble ceramic;

              The molecules of the marble are bounded slightly less than than graphite molecules so the  spectrum is little distinct. The blue light seems to have a spread out.

                                      Fig 1(b) spectrum 14 February, White ceramic;

               The molecules of the ceramics are bounded softer than Marble so the spectrum obtained here is weaker when compared to Marble. The dominant blue light is very interesting.

                              

                                        Fig. 1(b) spectrum 14 February, Blue ceramic;

               The molecules are bound softer than white ceramic, so the spectrum obtained is weaker than spectrum of White ceramic. Predominant Red and Green lights are very distinct.

FROM VISAKHAPATNAM

                                       

Fig.2a spectrum 16 February, Graphite ceramic; 00.20am

             The spectrum of granite which appears little bit blurred because of the volcanic clouds passing by the moon . The yellow light is extremely feeble.

Fig.2b   spectrum 16 February, White ceramic; 00.22am

               The White ceramic spectrum appears quite sharp and almost overlapping due to the volcanic clouds passing by the moon. Interesting is the Yellow light dominance.

CONCLUSIONS

            
                  We define a new quantity named lortusity as the ratio of the real path length to the apparent path length in a ceramic material. Since the findings are based on the light intensity variations with coupled movement of intense Volcanic and other preliminary affects of it. For example the Fig. 2b shows very sharp spectrum while the Fig. 2a shows the broadened spectrum.

           

            The porosity of the ceramic samples cannot be neglected and we have intelligently chosen the samples from tough granite to loose-fitting other ceramics. The ‘connectivity‘ of pore space, viz., the number of pores meeting at a point, in a porous media by regular packing is predominant in graphite.  Further discussion on the nature of porosity and details of it are to be specified explicitly in my thesis work. The details form the subject of extensive research investigation of Ph. D Degree in Physics, by the author.
