In solids, sound is propagated in the form of longitudinal and transverse waves. However, there is a considerable difference in the speed of the two types of sound waves, since longitudinal sound waves are determined by the elastic ... more

Objective: Determine band separation in germanium Semiconductors only exhibit measurable electrical conductivity at high temperatures. The reason for this dependence on temperature is the band structure of the electron energy levels ... more

Objective: Investigating electrical conduction mechanisms in doped germanium with the Hall effect The Hall effect occurs in electrically conductive materials located in a magnetic field B. The Hall voltage’s sign changes depending ... more

Objective: Record the characteristic curve for a photoresistor Photoconductivity utilises absorption of light by means of the inherent photoelectric effect in a semiconductor to create electron-hole pairs. One specific semiconductor ... more

Objective: Record characteristics for various thermocouples and determine their sensitivity If the ends of a metal wire are at different temperatures, since the thermally generated motions of the electrons have different velocities, ... more
