Dual Nature Of Light Question 501

Question: The ratio of the energy of an X-ray photon of wavelength 1 Å to that of visible light of wavelength 5000 Å is [EAMCET (Med.) 1995]

Options:

A) 1: 5000

B) 5000 : 1

C) 1 :25 $ \times $ 106

D) 25 $ \times $ 106

Show Answer

Answer:

Correct Answer: B

Solution:

Energy $ E=h\nu =h\frac{c}{\lambda } $
$ \therefore \frac{E_{1}}{E_{2}}=\frac{{\lambda_{2}}}{{\lambda_{1}}}=\frac{5000}{1} $
