Consider two beams of light. The first beam
has a wavelength of 280 nm with an
intensity of 3.50 Wm? and the second has a
wavelength of 175 nm with an
intensity of 120 W/m? Each beam strikes an
identical metal surface, causing
electrons to be emitted. Do the following:
• Determine which beam will eject electrons
with more kinetic energy. Defend
your answer!
• Find the energy in el of a photon of this light.
