Question

How can we use the y-intercept and the slope from the graph to determine Planck's Constant and the work function in the equation KEmax​=hf−ϕ ?
(Note: I know the linearization is showing the y-int. and slope to be zero because the values are so small, but conceptually how could we do it?)

Answer 1

Griveni KEmax = hf - we can it by general q Now compare linear equation ya -mat where m = slope ah с intercept = -6
