Question

The photoelectric equation is
  1. hv=hv0Ek
  2. hv=hv0+Ek
  3. hv=hv0
  4. kv=hv0+EkV

A
kv=hv0+EkV
B
hv=hv0
C
hv=hv0Ek
D
hv=hv0+Ek
Solution
Verified by Toppr

The photoelectric effect related with the
incident light frequency (ν) by the following equation:
Ek=eVs=hνϕ,
where ϕ=hν0 is the work function of the material and Ek is the kinetic energy of the photo electron.
So, Ek=hνhν0
or, hν=hν0+Ek
So, the answer is option (C).
