-ray tube operates on 30 kV. What is the minimum wavelength emitted ( 
Coulomb, 
)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
For an accelerating voltage 
, the maximum 
-ray photon energy is given by
The minimum wavelength corresponding to this maximum energy is 
where 
is Planck's constant and 
is speed of light.
