Newton's Rings - Fringe Desk Mat

$44.99

Newton's rings — the interference pattern in a thin air film between a curved lens and a flat plate.

Concentric rings whose radii grow as the square root of the ring number, dark at the centre because the reflection off the denser glass flips the phase by pi. Computed from the wave. Full-bleed XL desk mat, 16" x 32", non-slip base. Part of the Fringe series.
