Dear sir,
I gave a fiitjee test in which the following question was asked
Q. Which of these can produce x-rays:
a)an energetic electron is decelerated
b)electron jumps from higher energy state to lower energy state in Bohr atom
c)an electron of k shell is captured by the nucleus(k electron capture)
d)a mew meson is captured by a proton to forma mesonic atom
All 4 options are given correct
I dint understand the meaning of the 4th option.Sum1 please tell me how it emits x-rays.
Also, how can the second option be correct??
Even if we consider Be3+ ion, the maximum energy difference between 2 levels is 13.6*16
If we use
13.6*16=hc/lambda,
lambda comes out to be 90/16 nm
approx. = 6 nm. Whereas x-rays hav wavelengths of the order of 0.1 nm
Then how can an electronic transition produce x-rays in a bohr atom?????
