Given below are two statements:
Statement I: Figure shows the variation of stopping potential with frequency 
for the two photosensitive materials 
and 
. The slope gives value of 
, where 
is Planck's constant, 
is the charge of electron.
Statement II : 
will emit photoelectrons of greater kinetic energy for the incident radiation having same frequency.
In the light of the above statements, choose the most appropriate answer from the options given below.
Text Solution
Verified by ExpertsB
Slope of the graph between stopping potential 
and frequency 
equals 
(using Einstein's photoelectric equation).
For material 
, emitted electrons will have greater kinetic energy. This is because 
has lower threshold frequency and thus have lower value of 
.
