In a photoelectric cell, the wavelength ...

In a photoelectric cell, the wavelength of incident light is changed from `4000Å` to `3600Å`. The change in stopping potential will be:

A

0.14 V

B

0.24 V

C

0.35 V

D

0.44 V

Text Solution

Verified by Experts

The correct Answer is:
C
`eV_(S)=hv-phi_(0)`
`eV_(s)=hv.- phi_(0)`
`:.e(V_(s)-V_(s))=h(v.-v)`
`:.V_(s).-V_(s)=(h)/(c)(v.-v)=0.35V`
