Consider the following statements
1. The Earth receives the Sun’s energy at the infrared end of the spectrum.
2. The Earth re-radiates the Sun’s heat as ultraviolet energ
Which of the statement(s) given above is/are correct?
Both 1 and 2
Neither 1 nor 2
The sun radiates vast quantities of energy into space, across a wide spectrum of wavelengths. Most of the radiant energy from the sun is concentrated in the visible and near-visible parts of the spectrum. The narrow band of visible light, between 400 and 700 nm, represents 43% of the total radiant energy emitted. Wavelengths shorter than the visible account for 7 to 8% of the total, but are extremely important because of their high energy per photon. The shorter the wavelength of light, the more energy it contains.
