Chaya Someswara Swamy temple :
Chaya Someswara Swamy temple, also known by the name Thrikutalayam, is a Hindu temple located in Panagal, Nalgonda district, Telangana, India.
It is a popular site during Sivarathri.
The temple was built in 11th - 12th centuries during Ikshvaku Dynasty.
The so-called chaya (vertical shadow) that falls on the deity looks like a shadow of one of pillars carved in front of the sacred chamber.
But it is not actually the shadow of any pillar. It is a dark region where light does not fall.
It is formed by the door sill (entrance) of the same chamber. Light enters the chamber through entrance from two sides.
The gap between two light exposed areas inside looks like a shadow of a pillar.
The local people try to find their shadow beside the chaya by touching one of the pillars. but they can see only a blurred shadow instead. You need to touch the entrance (door sill) of the chamber to see your shadow beside chaya.
The eleventh century architect might not be aware of wave properties of light but he constructed the temple in such a way that the light enters the inner chamber through two narrow gapes between pillars and wall on either side of entrance and diffracts. The diffracted light enters the chamber making shadow of edges of entrance crisscrossing one with another leaving a gap between them.
