Question
Which of the following forms of radiation can be shielded by Earth’s atmosphere?Group of answer choicesRadio wavesVisible lightAll of the aboveGamma rays
Solution
The Earth's atmosphere can shield us from certain forms of radiation.
-
Radio waves: These are a type of electromagnetic radiation with wavelengths that range from about one millimeter to 100 kilometers. They can pass through the Earth's atmosphere without being absorbed or reflected, which is why we can receive radio signals from distant radio stations and satellites.
-
Visible light: This is also a type of electromagnetic radiation, but with a much shorter wavelength than radio waves. The Earth's atmosphere allows most visible light to pass through, which is why we can see the sun and the stars.
-
Gamma rays: These are a type of high-energy electromagnetic radiation, with much shorter wavelengths than visible light. The Earth's atmosphere absorbs most gamma rays, preventing them from reaching the surface and causing harm to living organisms.
So, the answer to your question is "All of the above." The Earth's atmosphere can shield us from all these forms of radiation to varying degrees.
