per item
When a laser beam is directed at a hair, the hair acts like an obstacle that splits the light into two coherent sources separated by the hair’s thickness. The light diffracts around the edges of the hair and interferes constructively and destructively, creating a clear pattern of bright and dark fringes on a screen or wall.
