Q: Why can't Moonlight ignite?

A: I can come up with the answer. I believe you must be a friend who is diligent in review.Remember to focus on the focus: Moonlight cannot be ignited like the sunlight, mainly because the second law of thermodynamics- "cannot be used to make the temperature of the incident object higher than the light source itself."The surface temperature of the moon is generally only 107 ° C. This temperature, even if it does not consume a little energy during the transmission process, does not reach the burning point of a piece of paper, let alone the atmosphere of 1,000 kilometers in the middle!
