Dual Nature Of Light Question 529
Question: Solid targets of different elements are bombarded by highly energetic electron beams. The frequency (f) of the characteristic X-rays emitted from different targets varies with atomic number Z as [AIIMS 2005]
Options:
A) $ f\propto \sqrt{Z} $
B) $ f\propto Z^{2} $
C) $ f\propto Z $
D) $ f\propto {{Z}^{3/2}} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \lambda \propto \frac{1}{Z^{2}}\Rightarrow \frac{c}{\nu }\propto \frac{1}{Z^{2}}\Rightarrow \nu \propto Z^{2} $
