Re: Photoelectric Effect
The photoelectric effect has to be done in a vacuum because it allows all frequencies to reach/travel to the sample.

Re: Photoelectric Effect
The photoelectric effect needs to be carried out in a vacuum because it will prevent less collision between the photo electrons and air molecules, which in turn will prevent energy loss.

Re: Photoelectric Effect
The photoelectric experiment has to be done in a vacuum because electrons produced close to the threshold have a relatively low energy. Low energy electrons cannot travel very far in the air before they are defected by collisions and this makes then very difficult to detect without a vacuum.
