A fringe pattern is formed on an observation screen in a double slit experiment by light of a single wavelength. What is the path length difference between the light travelling from each slit, for the dark fringe right next to the bright central maximum? OVA wavelength V wavelength 1 wavelength 1% wavelengths 2 wavelengths QUESTION 10 An experimenter shines different colors of light on a metal surface and measures the number of electrons emitted from the metal and the maximum kinetic energy of the electrons. What will the experimenter observe when using green light with a wavelength of 550 nm versus blue light with a wavelength of 450 nm? Assuming the same total intensity of the light for both colors. The blue light results in more emitted electrons with a higher maximum kinetic energy relative to the green light. The blue light results in more emitted electrons with a lower maximum kinetic energy relative to the green light. The blue light results in fewer emitted electrons with a higher maximum kinetic energy relative to the green light. The blue light results in fewer emitted electrons with a lower maximum kinetic energy relative to the green light. Neither the number of electrons or the kinetic energy is affected by the wavelength of the light.
