Atomic Structure Question 37
Question: The energy of a radiation of wavelength $ 8000,{\AA} $ is $ E_1 $ and energy of a radiation of wavelength $ 16000{\AA} $ is $ E_2 $ . What is the relation between these two [Kerala CET 2005]
Options:
A) $ E_1=6E_2 $
B) $ E_1=2E_2 $
C) $ E_1=4E_2 $
D) $ E_1=1/2E_2 $
E) $ E_1=E_2 $
Show Answer
Answer:
Correct Answer: B
Solution:
$ E\propto \frac{1}{\lambda }\ ;\ E_1=\frac{1}{8000}\ ;\ E_2=\frac{1}{16000} $
$ \frac{E_1}{E_2}=\frac{16000}{8000}=2\ \ \Rightarrow \ E_1=2E_2 $
