Interference With Eclipse

Here is one of the most spectacular picture taken during the Partial Solar Eclipse on July 22nd, 2009 at Hong Kong. The picture shows a very rare and unusual pattern of sunlight. The pattern seen here is known as the Interference Pattern. This is caused due to the superposition of the direct sunlight and the light reflected from the  window grids of the building on the left. (To know more about Superposition of light, check your 12th Physics Book ). This picture was taken from the 27th floor of a building.
