Photoelectric Effect

Let's start out super easy. What does eV mean?

A.Electrical Volt

B.Electron Velocity

C.Electron Volt

D.Electrical Velocity

E.Effort Value

Continuing to keep it simple, what is Planck's constant?

That's enough warm up, lets get onto the topic itself. What does the photoelectric effect prove?

I shine my red laser pen for my cat, Bradley, to chase around like the complete idiot he is. How much energy does the beam carry?

Which statement is true about the work function?

So I whipped up a quick graph to show you guys, but I worry I made an error. In fact I know I did because I did it intentionally for this question. Anyway, can you tell me what it is?

A.

B.

C.

D.

Say I decide to shine a light at a photoelectric surface because why wouldn't I? It has a a frequency of 570THz. The electrons are released with a velocity of 360000ms-1. What is the work function of the surface?

What is the correct definition of stopping voltage?

I get tired of writing questions so I decided to drink some mercury. However, I'm not sure if the substance I have on hand actually is mercury or not. All that I know is that the photoelectric work function of mercury is 4.53 eV, and when I shine a blue light of frequency of 650Thz the sample releases electrons of a KE 1E-19 J
