Ultraviolet light with a wavelength of 60nm shines on a gas

Reference no: EM13632098

Ultraviolet light with a wavelength of 60nm shines on a gas of hydrogen atoms in their ground states. Some of the atoms are ionised by the light. What is the kinetic energy of the freed electrons in this process?

KE = mv2

E = hv

v = c/λ

(dont know how to find velocity to find KE
