Solution
Solution Steps
Step 1: Understanding the Sun's Radiation
The Sun emits a broad spectrum of electromagnetic radiation, including ultraviolet (UV), visible light, and infrared (IR) radiation. However, the majority of the Sun's energy output is in the form of visible light, with significant portions in the UV and IR ranges as well.
Step 2: Understanding the Earth's Radiation
The Earth absorbs energy from the Sun and re-emits it primarily as infrared (IR) radiation. This is because the Earth is much cooler than the Sun, and according to Planck's law, cooler objects emit radiation at longer wavelengths, which is in the infrared range.
Step 3: Evaluating the Statement
The statement claims that the Sun primarily gives off UV radiation and the Earth primarily gives off IR radiation. While it is true that the Earth primarily emits IR radiation, the Sun primarily emits visible light, not UV radiation. Therefore, the statement is incorrect.
