Light rays of every frequency strike the Earth all the time. Some of the light is reflected back into space, from clouds or the oceans; some of the light is absorbed, which heats the Earth.
Some of the heat energy is re-radiated into space, especially on very clear nights. (If you have ever wondered why clear winter nights are so much colder than cloudy winter nights, this is why; the heat of the Earth is escaping into space! Winter clouds act as a blanket, trapping the heat close to the ground.)
So, high-frequency UV light is sometimes absorbed, while lower-frequency heat is re-radiated.
