If energy is radiated by all objects, why can we not see them in the dark? (See also Section 14-8 )
Solution 2Q: Energy is radiated by each and every body in the universe, above its absolute temperature then also we are unable to see an object in the dark as their wavelength does not lie in the visible spectrum region. Step 1 of 2 Concept: Visible Spectrum: The region(part) of the electromagnetic wave spectrum which is visible to the human eye is known as visible spectrum. Black Body Radiation: The rate of energy radiated by a black body depends on its temperature. The relation between energy and temperature is given by Stefan-Boltzmann law. According to Stefan-Boltzmann law, rate of energy radiated by the body is directly proportional to the fourth power of its Kelvin temperature. Mathematically, dQ 4 dt T Quantum Law: Energy (E) of an electromagnetic radiation is inversely proportional to the wavelength () of the radiation.
