Fitur

• This is a set that allows you to easily experiment with photoelectric effects using a battery tester using a handy-type ultraviolet light device or a black light.
• Observe how the foil closes when the light of an ultraviolet light device or a black light is brought close to the detector.
• It can be confirmed that there is a difference in the photoelectric effect of the metal plate, and that the closure of the foil differs depending on the wavelength of the light to be irradiated.
• * Electrical inspection equipment is not included.
