C) 2 : 1
D) 1 : 2
Correct Answer: C
Solution :
From the formula of work function \[{{W}_{0}}=\frac{hc}{\lambda }\] here \[{{\lambda }_{0}}\] is threshold wavelength \[\frac{{{W}_{01}}}{{{W}_{02}}}=\frac{{{\lambda }_{02}}}{{{\lambda }_{01}}}=\frac{600}{300}=\frac{2}{1}\]You need to login to perform this action.
