Laser Slits Reveal Wave Patterns

Laser light can reveal wave behavior through interference and diffraction. These are common wave effects seen in many settings, from water waves to electromagnetic waves such as light.

Interference happens when two waves of the same kind overlap. Their combined wave creates a repeating pattern of...

Interference and diffraction are characteristic phenomena of all waves, from water waves to electromagnetic waves such as light.

Interference refers to the phenomenon where two waves of the same kind overlap to produce a resultant wave of greater, lower, or the same amplitude.

Diffraction is defined as the bending of a wave around th...
