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:
1:1
1:2
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} $
