In a photoelectric effect experiment, the graph of stopping potential V versus reciprocal of wavelength λ of incident light for a given material is plotted below.
If the existing material is replaced with another material and the intensity of the light is increased, which of the following is most likely to happen?
A. The slope theta of the line will increase.
B. The slope theta of the line will decrease.
C. There will not be any change in the graph.
D. The line will cut the 1/λ axis at a different point.
