Three graphs illustrate types of light wave interference. The top shows constructive interference with two waves combining to form a larger wave. The middle shows partial destructive interference, where the waves partially cancel, resulting in a smaller combined wave. The bottom shows complete destructive interference, where two waves of equal amplitude and opposite phase cancel each other out, resulting in a flat line.

Four line graphs illustrate the superposition principle in voltage analysis. The top left graph shows two voltage signals, V1a and V2a, as square waves over time. The top right graph shows V1b and V2b as curved voltage signals over time. The bottom left graph displays the combined voltage Va, equal to V1a plus V2a, with a brief voltage spike. The bottom right graph shows Vb, the sum of V1b and V2b, producing a stepped voltage response over time. All graphs plot volts versus time in milliseconds.
