The Experimental Setup Consists of Experimental Study of Photoelectric Effect #8211; (i) Monochromatic light of short wavelength (meaning high frequency). (ii) Battery to accelerate emitted electrons through a potential difference. (iii) Voltmeter to measure the potential difference between the emitter and the collector plates due to photoelectric current flow. (iv) Ammeter to measure the value of photoelectric current. (v) Photosensitive plate (emitter) to absorb visible light and emit electrons.
