The maximum kinetic energy of a photoelectron liberation from the surface of lithium with work function 
by electromagnetic radiation whose electric component varies with time as :
(where 
is a constant) is 
, and 
and Planck's constant 
)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Here, work function, 
and the electric component of electromagnetic radiation
So, the maximum kinetic energy of photoelectron, we take photon of maximum frequency, Hence,
Hence, the maximum kinetic energy,
