Dual Nature Of Light Question 222
Question: The energy of a photon of light with wavelength 5000 Å is approximately 2.5 eV. This way the energy of an X-ray photon with wavelength 1Å would be [MP PET 1997]
Options:
A) 2.5/5000 eV
B) $ 2.5/{{(5000)}^{2}}eV $
C) $ 2.5\times 5000\ eV $
D) $ 2.5\times {{(5000)}^{2}}eV $
Show Answer
Answer:
Correct Answer: C
Solution:
$ E\propto \frac{1}{\lambda }\Rightarrow \frac{2.5}{E’}=\frac{1}{5000}\Rightarrow E’=(2.5)\times 5000\ eV $
