A GHOST OR SPIRIT ?( MY NEW DISCOVERY ):

ONE DAY IN THE NIGHT, I WAS WALKING ON THE ROAD SIDE.SUDDENLY I SAW DUSTS BLOWN BY AIR ON THE ROAD.


SUDDENLY I SAW AN ILLUSION ( A GHOST LIKE IMAGE ) RUNNING TOWARDS ME.FOR A SECOND I WAS SHOCKED.AFTER SOME FEW SECONDS I  SAW A PERSON TOO  RUNNING TOWARDS ME.


BEHIND HIM A CAR WAS COMING ,FLASHING A BEAM OF LIGHT ON HIM.IS THAT IMAGE A GHOST ? HOW DID IT FORM? SO MANY QUESTIONS ROSE FROM MY MIND AT THAT SPOT.

AT LAST I FOUND THE ANSWER.ACTUALLY WHEN THE LIGHT RAYS FALL ON THAT PERSON ,RAYS BEND ON THE EDGES OF THAT PERSON ( FROM HEAD TO FOOT ) AND HAS BEEN  MAGNIFIED ( GROWN BIGGER) {THIS IS SIMILAR TO THE PHENOMENON OBTAINED WHEN WE STAND BEFORE A CANDLE IN THE DARK, OUR DARK IMAGE WILL APPEAR BIGGER AS WE MOVE TOWARDS IT}.

THIS MAGNIFIED IMAGE OF THAT PERSON FELL ON THE BLOWN DUSTS AND FORMED AS AN ILLUSION LIKE PICTURE,WHOSE APPEARANCE IS SAME ( BUT NOT SIMILAR IN SIZE ) AS THAT OF THE PERSON RUNNING BEFORE THE CAR.

SO THE PHENOMENON BEHIND THIS EVENT IS DIFFRACTION EFFECT.THAT IS " BENDING OF LIGHT AROUND THE EDGES OF AN OBSTACLE "
