wording of questions (maybe just for Kaplan?)

Members don't see this ad.

one of the Kaplan questions was regarding increasing the number of electrons ejected from "a certain metal plate illuminated by a monochromatic light"

one of the correct responses was to increase area, but I didn't mark this because I didn't know I have to assume that it would still fully illuminate a bigger area..

when dealing with questions, do you guys assume that everything else is true about the question? I feel like this pertains a lot to verbal questions too.. maybe I'm just a poor test taker 🙁

What was the exact question and other answer choices?

" A certain metal plate is completely illuminated by a monochromatic light source. Which of the following would increase the number of electrons ejected from the surface of the metal?

I. Increase intensity of light source
II. Increase frequency of light source
III. Increasing surface area of metal plate

I understand why intensity would and frequency wouldn't, but assumed that a bigger surface area would still leave the light hitting the initial area...

Is non of the above an answer choice? If not, then you don't have a choice but to assume the light would affect the larger area.

Either way, it's reasonable to assume that your light source is not a laser or something that isn't going to cover a larger area. The more questions you do the more you'll be able to identify the concept being tested. In this case the concept is that more area = more electrons.

ah yeah.. make sense.. i'm always suspicious of tricks..

thank you!
