When Sw 1, which is likely part of a circuit controlling the green light, is opened, it generally means that the circuit is no longer complete, which would usually lead to the light turning off. However, if the correct answer is that the light turns ON, this suggests there is a specific setup in the circuit that allows the light to activate under those conditions.

For instance, when Sw 1 is opened, it may trigger another component in the system that allows current to flow to the green light from a different source or through a backup path. This could happen in cases where opening the switch somehow redirects the circuit flow or activates a parallel connection that powers the light. Therefore, while it's common for lights to turn off when a switch is opened, this unique scenario indicates an alternate operational mode of the circuit where the green light is activated instead, leading to it turning ON right after the switch is opened. This highlights the importance of understanding circuit behavior and the specifics of how different components interact within an electrical system.
