Supplier: PHYWE

Equipment for demonstrating photoelectric power and determining Planck's constant. A photocell is equipped with filters that only transmit light of a certain wavelength. The photocell is illuminated with light from a Hg lamp. The potassium cathode then emits electrons that pass over to the unlit anode. Over time, a voltage arises that prevents new electrons from reaching the anode. The resulting voltage is measured with a measuring amplifier and a voltmeter. The measurement is repeated with filters for different wavelengths. Photocell and Hg lamp are equipped with magnets at the bottom for stable installation on the mounting plate. List of equipment.
