What is the ratio of the energy of an X ray photon of wavelength 1 Å to that of visible light of wavelength 5000 Å ?

A

`5000:1`

B

`1.25xx10^6`

C

`25xx10^6`

D

`1:5000`

Text Solution

Verified by Experts

The correct Answer is:
A
`E = hv = (hC)/(lamda)`
`therefore E_1/E_2 = lamda_2/lamda_1 = (5000)/(1) = 5000 : 1`
