The earth absorb radiation in Visible range but emit radiation at the same rate in the:
Correct answer: C. Infrared
- A. Ultra voilet
- B. Gamma rays
- C. Infrared
- D. All of these
Explanation
The Earth receives much of the Sun’s incoming energy in visible and shorter-wavelength radiation, but its cooler surface emits mainly longer-wavelength infrared radiation. This follows from thermal radiation: a cooler body has its peak emission at a longer wavelength. Students may choose ultraviolet because it is also solar radiation, but Earth’s temperature is not high enough to emit mainly ultraviolet.

About Planck's Quantum Theory
Planck's quantum theory states that energy is emitted or absorbed in discrete packets called quanta, with each packet having energy E = hν. It covers the meaning of Planck's constant, the relationship between frequency and wavelength, and how quantisation differs from the classical continuous model of energy.
