For example, what is the reason why greenhouse gases reflect heat from the Earth back to Earth, but not heat from the Sun back to the space?
From what I understand, it has something to do with radiation and emitted waves, but what exactly makes the difference?

If I have a bright LED it might not be that warm and light doesn’t heat the air much. But if shine it at a black wall, the temperature starts to rise. Because when something “absorbs light” it turns it into heat. The sun puts out a ton of visible light and even higher energy UV light that isn’t exactly hot on its own, until it hits something like the earth, at which point it turns into more heat.
