When ultraviolet light with a wavelength of
400 
falls on a certain metal surface, the maximum kinetic energy of the emitted photoelectrons is
1.10 
.

What is the maximum kinetic energy  of the photoelectrons when light of wavelength 310  falls on the same surface? |
Use

=
6.63×10−34 
for Planck's constant and

=
3.00×108 
for the speed of light and express your answer in electron volts.
