When radiations of wavelength `lamda_(1) and lamda_(2)` are incident on certain photosensitive material, the energies of electron ejected ar `E_(1) and E_(2)` respectively, such that `E_(1)gt E_(2),` Then Planck's constant 'h' is (C = velocity of light)

A

`((E_(1)-E_(2))(lamda_(1)-lamda_(2)))/(C(lamda_(1) . lamda_(2)))`

B

`((E_(1)-E_(2))lamda_(1)C)/((lamda_(1)-lamda_(2))lamda_(2))`

C

`((E_(1)-E_(2))lamda_(1) lamda_(2))/(C(lamda_(2)-lamda_(1)))`

D

`((lamda_(2)-lamda_(1))C)/((E_(1)-E_(2))lamda_(1).lamda_(2))`
