Homework Help: chemistry

Posted by bill on Friday, September 3, 2010 at 11:28pm.

We conduct an experiment by shining 500
nm light on potassium metal. This causes electrons to be emitted from the surface via the photoelectric effect. Now we change our
source light to 450 nm at the same intensity level. Which of the following is the result from
the 450 nm light source compared to the 500 nm source?

I said that more electrons would be emitted. Is that correct? Thanks.
