What did people get for the last question 1.91x10^26 or 27 i dont exactly remember. Also, what about the work function one? DId people say the light can be detecetd as it exceeded threshold frequency? And were everyone able to draw the lens diagram.

Screwed up the lenses and some of the space stuff but the rest went ok

yeah i got both of those answers, i wasnt too sure on the lens diagram though i just drew the standard lines and rolled with it

for the work function one, i got the energy to be slightly higher than the work function, (0.32 or something) and i think that means it works becasue photoelectrons can be emmitted
