When photons of wavlength `lambda_(1)` are incident on an isolated sphere suspended by an insulated thread, the corresponding stopping potential is found to be `Delta V.` When photons of wavelength `lambda_(2)` are used, the corresponding stopping potential was thricle of the above value. If light of wavelength `lambda_(3)` is used, the stopping potential for this case would be

Options

A. `(hc)/(e)[1/(lambda_(3))+(1)/(2lambda_(2))-(1)/(lambda_(1))]`
B. `(hc)/(e)[1/(lambda_(3))-(1)/(lambda_(2))-(1)/(lambda_(1))]`
C. `(hc)/(e)[1/(lambda_(3))+(1)/(lambda_(2))-(1)/(lambda_(1))]`
D. `(hc)/(e)[1/(lambda_(3))+(1)/(2lambda_(2))-(1)/(2lambda_(1))]`
