CAPE Physics Unit 2 · 2002 · Paper 2 · Question 3(a)(ii)

A photoelectric effect experiment with light of wavelength 500 nm and intensity 1.0 μW cm^-2 produces current and potential difference measurements listed in Table 1.

From the plotted graph, record the stopping potential for the metal.

This question uses a figure or table from the paper — you'll see it when you practise.
