Item no.: XWV590012 New and updated for 2015. This compact unit provides an elegant method of demonstrating the wave phenomena of reflection, diffraction, refraction and interference with none of the setting-up problems usually associated with ripple tanks. The concept has been further developed to offer new features and simplicity in this MkIII design. The unit is
Item no.:XAR260010 A new and improved spark detector gives a memorable and dramatic demonstration of the ionising properties of alpha particles. Alpha particles have short range but are very effective at ionizing air. In this apparatus a number of fine wires are supported above a metal plate to form two electrodes separated by a small
Item no.: XAR040010 The Lascells cloud chamber is the perfect alternative to existing unreliable and time consuming dry ice variants. The chamber is self-contained and thermoelectrically cooled. The chamber requires no dry ice; the only setup necessary is the addition of isopropyl alcohol and connection to a mains socket. The chamber contains an integrated power supply
Item no.: YAS490010 The gravity well is an exciting piece of apparatus which allows students to visualise the attraction of massive objects due to gravity. Consisting of a flexible sheet and collapsible frame, the gravity well is supplied with all you need to bring the study of gravity to life. • Coalescence of stars • Orbiting
Item no.: F22 Introduction Rather than the energy continuity considered in classic physics, the energy level of a photon or an electron, viewed from quantum theory, exhibits an integer multiple of hf (here h is planks constant and symbol of f indicates the frequency of light wave). That means a light is emitted from or
Item no.: F23 Introduction In general, light spectrum could be classified into discrete spectrum and continuous spectrum. However, both absorption and emission are the main typical pattern for discrete spectrum. Unlike the discrete way mentioned above, typical continuous spectrum, in this experiment, will be investigated. Here a slice with 500line / mm grate will be
Item no.: F19 RLC circuit has a very important feature, that is, the produced amplitudes of circuit-current will closely depend on the input frequency. Generally speaking, partial signal will be filtered, but partial might be augmented as several power sources with different frequency, in the circuit, are delivered simultaneously. Here amplified signal of frequency is
Item no.: F18 Introduction In1820, an electromagnetic theory was initiated by Oersted. Here the physical experiment relative to magnetic field induced by a current-carry wire was proposed. During 1820~1827, the theoretic model was further quantified by Ampere’s. In 1831, the so called Faraday’s law amounted the current induced along the closed loop while a time
Item no.: F17 Introduction Base on Coulomb’s law, the magnitude of electric field E produced by single charge Q might be given below, which induce an irradiated outward electric field for + Q or irradiated inward direction of electric field for – Q. While consider the work done of charged particle moving in the electric
Item no.: F06 Introduction Just for the twentieth century, the electricity, widely used for a variety of applications, has played a significant role in our daily life. In this experimental kit, students could learn how to constitute circuit loop without breadboard needed, which makes the experiment undertaken easily. In addition, teacher’s demonstration on teaching board
