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 Be 3+ 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?????

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?????
