This image shows an interference pattern typical of a double-slit experiment, which demonstrates the wave-like behavior of light. The pattern is characterized by alternating dark and bright vertical fringes. 

- **Bright Fringes:** These are the result of constructive interference, where waves from the two slits arrive in phase and reinforce each other, creating areas of higher intensity.

- **Dark Fringes:** These are areas of destructive interference, where waves from the two slits arrive out of phase and cancel each other out, resulting in minimal or no light.

This interference pattern is a key demonstration of the principle that light behaves as a wave, as explained in wave-particle duality in physics.
