Excuse me, why is the shadow of this branch like a ripple? Is it an optical phenomenon?

It involves the propagation of light along a straight line and the interference of light. Oh, when multiple beams of light pass through branches and leaves, they will interfere with each other due to the wave-particle duality of light, resulting in different light and shadow, which looks very blurred.
