    Complete question:

    Two spotlights point towards a stage. Where the spotlight intersect, the light appears to be brighter. How does this phenomenon support the wave model of light?

    A. It’s the result of refraction

    B. It is the result of interference

    C. It is the result of the Photoelectric effect

    D, It is the result of blackbody radiation

    Answer:

    B. Interference

    Explanation:

    Interference is based on the wavy nature of light. The interference of two or more luminous waves is the interaction between them. The luminous waves combine when they meet at the same point in space, and their effects superpose. This interaction produces a new wave that is the sum of its components. Those waves that are in phase reinforce each other, while those opposite ones are canceled. The interference event will be noticeable if the involved waves propagate in the same direction and keep constant the phase difference.
