Question

The photoelectric threshold wavelength of silver is 3250 XT-
10-10 m. The velocity of the electron ejected from a silver
surface by ultraviolet loght of wavelength 2536 x 10-10 m is
(Given h =4.14 x 10-15 eVs and c = 3 x 108 ms -1)
[NEET - 2017]
(1) = 6 x 105 m/s-1
(2) = 0.6 x 106 m/s-1
(3) = 61 x 103 m/s-1
(4) 0.3 x 106 m/s-1​
