Graph of stopping potential for most energetic emitted photoelectron `(V_(S))` with frequency of incident radiation on metal is given below.

The value of `(AB)/(BC)`, in graph is
(h=Planck's constant, e = electronic charge)

A

h

B

e

C

`(h)/(e)`

D

`(e)/(h)`

Text Solution

Verified by Experts

The correct Answer is:
C
By Einstein's photoelectric equation
`KE_("max")=eV_(s)=hv-hv_(0)`
`implies" "V_(s)=((h)/(e))v-(hv_(0))/(e)`
Graph of `V_(s)` with v is straight line whose slope = `(h)/(e)`
Slope of graph `=(AB)/(BC)implies (AB)/(BC)=(h)/(e)`
