Question

If the earth did not have atmosphere, would its average surface temperature be higher or lower than what it is now? Explain.

Solution

In the absence of atmosphere, there would be no greenhouse effect on the surface of the Earth. As a result, the temperature of the Earth would decrease rapidly, making it difficult for human survival.

In an atom X, electrons absorb the energy from an external source. This energy “excites” the electrons from a lower-energy level to a higher-energy level around the nucleus of the atom. When electrons return to the ground state, they emit photons.

The figure below is the energy level diagram of atom X with three energy levels, E1 = 0.00eV, E2 = 1.78eV and E3 = 2.95eV. The ground state is considered 0 eV for reference. The transition of electrons takes place between levels E1 and E2.

  1. What wavelength of radiation is needed to excite the atom to energy level E2 from E1?
  2. Suppose the external source has a power of 100 W. What would be the rate of photon emission?
