The energy levels of an atom are as shown in Fig.1.23 Which one of these transitions will results in the emission of a photon of wavelength 275 nm? .

The energy level diagram of an element is given below. Identify by doing necessary calculations, which transitions corresponds to the emission of a spectral line of wavelength 102.7nm

The energy levels of an atom of element X are shown in the diagram. Which one of the level transitions will result in the emission of photons of wavelength 620 nm ? Support your answer with mathematical calculations.

If the lowest energy X-rays have lambda=3.055xx10^(-8) m, estimate the minimum difference in energy between two Bohr's orbits such that an electronic transition would correspond to the emission of an X-ray. Assuming that the electrons in other shells exert no influence, at what Z (minimum) would a transition form the second level to the first result in the emission of an X-ray?

The energy liberated in the ecombination of hole-electron pair is converted into electromagnetic radiation. If the maximum wavelength emitted is 500 nm, find value of forbidden energy gap.

Calculate the photon energy in electron- volt for radiation of wavelength 1 metre.
