A strange metallic rock is found and is being tested. Suppose that light with a frequency of 9.40 ✕ 1014 Hz is incident upon the rock and a stopping potential of 1.50 V is needed to reduce the electron current to zero in a photoelectric experiment. What is the minimum frequency of light for which electrons are still ejected from the surface of this material? Hz
