Dual Nature Of Light Question 374

Question: The ratio of energies of X-rays of the wavelength $ 0\text{.01}\overset{o}{\mathop{A}}, $ and $ 0\text{.5}\overset{o}{\mathop{A}}, $ will be

Options:

A) 1:1

B) 1:2

C) 1:5

D) 50:1

Show Answer

Answer:

Correct Answer: D

Solution:

[d] $ \frac{E_{1}}{E_{2}}=\frac{hc}{{\lambda_{1}}}\frac{{\lambda_{2}}}{hc}=\frac{{\lambda_{2}}}{{\lambda_{1}}}\Rightarrow \frac{E_{1}}{E_{2}}=\frac{50}{1} $
