When photon of wavelength `lambda_(1)` are incident on an isolated shere supended by an insulated , the corresponding stopping potential is found to be `V`. When photon of wavelength `lambda_(2)` are used , the orresponding stopping potential was thrice the above value. If light of wavelength `lambda_(3)` is used , carculate the stopping potential for this case.

Options

A. `(hc)/(e ) [ (1)/(lamda_3) + (1)/(lamda_2) - (1)/(lamda_1)]`
B. `(hc)/(e ) [ (1)/(lamda_3) + (1)/(2lamda_2) - (1)/(lamda_1)]`
C. `(hc)/(e ) [(1)/(lamda_3) - (3)/(2lamda_2) + (1)/(2lamda_1)]`
D. `(hc)/(e ) [ (1)/(lamda_3) + (1)/(2lamda_2) - (3)/(2lamda_1)]`

Answer

C

Explanation

`(hc)/(e ) [(1)/(lamda_3) - (3)/(2lamda_2) + (1)/(2lamda_1)]`
