Thanks! If I draw an arrow and put my answer for a part outside of where it was intended but still on the paper within the box where the paper is scanned, can it still be right or do they mark it wrong if not in the appropriate area?

I got the rankings on the first one right but i used logic that "photons with similar wavelengths as the electrons cause them to be ejected" 😭😭 may be cooked

[championinsights]

Why can't you use the equation v =f(wavelength) and say they are proportional therefore with higher wavelength comes higher velocity then higher ekmax

i stumbled straight into this frq knowing nothing but "hehe higher frequency particle = more energy particle hehe"

idk maybe i'll get 6 points here
