Light Wave Interference

Light wave interference occurs when two or more light waves overlap and combine. Depending on how their peaks and troughs align, they can either reinforce each other (constructive interference), creating brighter areas, or cancel out (destructive interference), resulting in darker regions. This phenomenon explains patterns like iridescence on soap bubbles or the colors seen in oil slicks. Interference depends on the waves' phases and wavelengths, illustrating that light behaves both as a wave and as particles, showcasing the complex and fascinating nature of light phenomena.
