Question

The photoelectric threshold wavelength of silver is 3250 $ \times $ 10^$-$10 m. The velocity of the electron ejected from a silver surface by ultraviolet light of wavelength 2536 $ \times $ 10^$-$10 m is
{Given h = 4.14 $ \times $ 10^$-$15 eV s and c = 3 $ \times $ 10⁸ m s^$-$1 ]

$ \approx $ 0.6 $ \times $ 10⁶ m s^$-$1

$ \approx $ 61 $ \times $ 10³ m s^$-$1

$ \approx $ 0.3 $ \times $ 10⁶ m s^$-$1

$ \approx $ 6 $ \times $ 10⁵ m s^$-$1
