On 9 December, there were classes in which we are acquainted with the concept of photon photoelectric effect. We performed two experiments.
Topic Experiment 1: Observation of the external photoelectric effect "
Observations:
plate electrified positively, as a further Punching electrons from the plate reduces the potential for a negative charge.
Conclusions:
With the deviation from the electroscope Lamp elapsed time to Sagging moment leaves was increased because fewer photons reach the plates per unit time.
glass absorbs part of the photon and it is not sufficient to cause the photoelectric effect. Experiment 2
Subject: Solar battery.
Wniosek1:
biggest bulb brightness is achieved when you shine on it perpendicular to its surface.
Wnisek2:
The larger the area illuminated, the more current flows through the bulb.
Wniosek3:
Photoelectric effect triggered by sources of varying light is not the same.
The higher intensity of radiation the greater the current through the bulb.
