Bronze glass table top is also included When two waves encounter each other, they make ‘interference pattern’.

Crest and trough create a resultant wave of greater, lower or the same amplitude in this superposition and these periodic pulses occur some natural patterns of beauty which we can discover in manifold nature circumstances. Crest and trough series are my physical works inspired by these interference patterns in waves.
