In this problem of the Final of RusPhO-2020, we need to measure the parameters of the cavity hidden inside the transparent disk. You can see the inscription “Final RusPhO 2020” on the box: the problem was originally developed for the 2020 olympiad, which did not take place due to the COVID pandemic. Оптический серый ящик …
This optical black box contains a mirror and a lens. We need to measure the lens focal length and determine how the mirror is positioned.
In this problem, you need to determine the power of a light emitted by a bulb. To do so, we measure the temperature of the black body heated by the lamp.
A set of four experiments with increasing difficulty, in which we should measure and interpret I-V curves. https://www.youtube.com/watch?v=mAWgILhu7EEhttps://www.youtube.com/watch?v=l9tY7N5Id14
In this experimental problem, we investigate the electric motor using a frequency meter.
In this experiment, we measure the heat capacity of several objects using a heater and Dulong–Petit law.
This set of equipment allows us to do two experiments. One of them allows us to determine which colors the white LED radiation consists of. The other allows us to measure the Planck constant by examining the radiation of a black body.
This experiment is about alternative energy. We study the LED and determine the solar battery efficiency.
В этой задаче исследуется резистор, сопротивление которого зависит от температуры. Нужно определить теплоемкость резистора, измеряя зависимость сопротивления от времени.
