Wavelength of photon having 35 keV energy will be……..`(h=6.625xx10^(-34))J-s,c=3xx10^(8)ms^(-1),1eV=1.6xx10^(-19)J)`.

A

`35xx10^(-12)m`

B

35Å

C

3.5nm

D

3.5Å

Text Solution

Verified by Experts

The correct Answer is:
A
`E=hf=(hc)/(lambda)`
`therefore =(hc)/(E )=(6.625xx10^(-34)xx3xx10^(8))/(35xx10^(3)xx1.6xx10^(-19))`
