#### Answer

No, in fact fewer electrons are emitted. Yes, each emitted photon has higher kinetic energy than before.

#### Work Step by Step

We know that the intensity (energy delivered per second to a given area) of the light beams is the same. The higher-frequency 400-nm photons each have more energy than the 450-nm photons. There are fewer 400-nm photons hitting the surface per second, so fewer electrons are ejected per second.
It still takes the same amount of energy (the work function) to eject each electron, so a higher-energy incoming photon means that the ejected electron will have more KE.
