Why is dark current not zero?

Why is the center of the ring dark?
Answer : The center of the ring appears dark due to **destructive interference** in a phenomenon called **Newton's rings** or other similar interference patterns. This happens when light waves reflect ... This effect is commonly observed in Newton's rings, soap bubbles, and thin-film interference patterns....
