Got this question during an interview - Without putting a camera inside the fridge. How would you check to see if the light turns off when you close the door.

I found this one answer on the internet -put a thermometer on the bulb and leave the door shut for 10 minutes. Then open the door and check the thermometer immediately. If it is cold, then you know the bulb was off when the door was closed.

Are there any other answers or the one listed above is the only answer.

Didn't know what category to choose so I selected science.
