Questions
For photo-electric effect with incident photon wavelength , the stopping potential is . Identify the correct variation(s) of with and .
a
b
c
d
detailed solution
Correct option is A
Kmax=E-w0 ⇒V0e=hcλ−w0 ⇒V0=hce1λ−w0e V0,1λ graph is in the from of y = mx – cOption C is correct.Clearly, V0,λ graph is a curve. V0 decreases with increase in λ. V0 becomes zero when hcλ=w0i.e. λ=λ0 (Threshold wavelength) Option A is correct.Talk to our academic expert!
