The electron in a `Li^(+ +)` ion is the nth shell , `n` being very large. One of the K-electron in another matallic atom has been knocked out. The second matel has four orbits. Now, we take two sample one of `Li^(+ +)` ion and the other of the second mateillic ions. Suppose the probability of electronic transition from higher to lower energy level is directly proportional to the energy difference between the two shells. Take `hc = 1224 eV nm` , where `h` is Planck's constant and `c` the velocity of light in vacuum. It is found that major electromagnetic wavws emitted from the two sample are identical. Now , answer the following questions:
The wavelength of this major X-ray is
