Item no.: P2320500 Principle A mass oscillates on a volume of gas in a precision glass tube. The oscillationis maintained by leading escaping gas back into the system. The adiabatic coefficient of various gases is determined from the periodic time of the oscillation. Tasks Determine the adiabatic coefficient of air nitrogen and carbon dioxide (and
Item no.: P2320300 Principle By means of the model apparatus for kinetic theory of gases the motion of gas molecules is simulated and the velocities determined by registration of the throw distance of the glass balls. This velocity distribution is compared to the theoretical Maxwell- Boltzmann equation. Tasks Measure the velocity distribution of the “model
(gas laws: Gay-Lussac, Amontons, Boyle) Item no.: P2320160 Principle The state of a gas is determined by temperature, pressure and amount of substance. For the limiting case of ideal gases, these state variables are linked via the general equation of state. For a change of state under isochoric conditions this equation becomes Amontons’ law. In
Item no.: P5160200 Principle An ultrasonic wave transmitted in a sample will be reflected at discontinuities (defects, cracks). From the relationship between the time of flight of the reflected wave and the sound velocity, the distance between ultrasonic transducer and defects (reflector) can be calculated. Position and size of these defects can be determined by
Item no.: P2151915 Principle Ultrasonic waves of the same frequency, amplitude and direction of propagation are generated by two sources of sound positioned parallel to each other. The sources can vibrate both in-phase and out of-phase. The angular distribution of the intensity of the waves, which interfere with each other, is automatically recorded using a
Item no.: P2151000 Principle A stationary ultrasonic wave in a glass cell full of liquid is traversed by a divergent beam of light. The sound wave length can be determined from the central projection of the sound field on the basis of the refractive index which changes with the sound pressure. Tasks To determine the
Item no.: P2132701 Principle If an oscillating system is allowed to swing freely it is observed that the decrease of successive maximum amplitudes is highly dependent on the damping. If the oscillating system is stimulated to swing by an external periodic torque, we observe that in the steady state the amplitude is a function of
Item no.: P5140100 Principle The ultrasonic Doppler effect is used for studying the laws of steadily and laminarly flowing liquids in a tube circuit, which form the basis of numerous technical applications. The experiment focuses particularly on the relationship between the flow velocity and the crosssectional tube area (continuity condition) as well as on the
Item no.: P2132000 Principle If the axis of rotation of the force-free gyroscope is displaced slightly, a nutation is produced. The relationship between precession frequency or nutation frequency and gyro-frequency is examined for different moments of inertia. Additional weights are applied to a gyroscope mounted on gimbals, so causing a precession. Tasks To determine the precession
Item no.: P2420600 Principle The electric constant is determined by measuring the charge of a plate capacitor to which a voltage is applied. The dielectric constant is determined in the same way, with plastic or glass filling the space between the plates. Tasks The relation between charge Q and voltage U is to be measured
