Reading appears on ammeter since electrons now have kinetic energy when they reach the plate.
This is because higher frequency leads to higher photoelectron KEmax

Did anyone get 2*10^-12 for the permittivity of the paped

yh i got that

same

Yessss thank you I love you

Love you too. But remember, we could both be wrong haha

Omg yeah!!

Doesn’t that give a relative permittivity that’s less than air?

hey people, don't actually do physics sorry for intruding on your thread. OCR Chem is on Monday though and I'm wondering how helpful the advance info was?

I didn’t I put values into C=EA/D to get E and then didvided that by relative permativity of free space which is 8.85x10^-12 to get like 2.6 or smtg but idk if that’s right tbh

Did it ask for relative permittivity??
