In the photoelectric effect experiment we use a Hg lamp to shine a light on a metal surface encased inside a photocell. There are multiple filters mounted on the front of the photocell to help us separate the light from the lamp into single-wavelength beams. Which of the following statements is true? Select one: a. Without the filters the photoelectric effect will still happen, but we will have no way to determine which electron was ejected by which photon wavelength....
