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 $
