When photons of wavelength \lambda_1 are incident on an isolated sphere, thecorresponding stopping potential is found to be V. When photons of wavelength \lambda_2 are used, the corresponding stopping potential was thrice that of the above value. If light of wavelength \lambda_3 is used then find the stopping potential for this case : [Main 9 Apr 2016]

Correct Answer is : hce[1λ3+12λ2−32λ1]

{hc}/e[1/\lambda_3-1/\lambda_2-1/\lambda_1]

{hc}/e[1/\lambda_3+1/\lambda_2-1/\lambda_1]

{hc}/e[1/\lambda_3+1/{2\lambda_2}-3/{2\lambda_1}]

{hc}/e[1/\lambda_3+1/{2\lambda_2}-1/\lambda_1]
