STANDARD Physics Greenhouse Effect MCQ Question
Which of the following electromagnetic wave play an important role in maintaining the earth’s warmth or average temperature through the greenhouse effect?
Visible rays
Infrared waves
Gamma rays
Ultraviolet rays
Correct Answer
Detailed Explanation
Infrared radiation plays an important role in maintaining the earth's warmth through the greenhouse effect. Incoming visible light when passes relatively easily through the atmosphere is absorbed by the earth's surface and radiated as infrared (longer wavelength) radiation. This radiation is trapped by greenhouse gases such as carbon dioxide and water vapour: In this way an average temperature is maintained.
