In photoelectric effect, stopping potential for a light of frequency `n_(1)` is `V_(1)`. If light is replaced by another having a frequency `n_(2)` then its stopping potential will be

`V_(1)-(h)/(e)(n_(2)-n_(1))`

`V_(1)+(h)/(e)(n_(2)+n_(1))`

`V_(1)+(h)/(e)(n_(2)-2n_(1))`

`V_(1)+(h)/(e)(n_(2)-n_(1))`
