What is the photoelectric effect?

Threshold Frequency

What happens if the incident light is below the threshold frequency?

What affects the threshold frequency?

Why do emitted electrons vary in KE up to a max?

Above the threshold frequency, what happens if you increase the intensity of the incident light? (What does it not do?)

Above the threshold frequency...What does increasing the frequency of the incident light do?
