7A10.10 - Photoelectric Effect7a1010photoelectric_effectIf you shine the UV light on a charged plate, the charge will leave the plate.
7A10.10-Photoelectric Effect with Neon Bulb

If you shine the UV light on a near powered neon light, the charge will induce the light (indicated by the light turning on.)
