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
Item no.: F20 Introduction Similar to light behavior, microwave, known as a style of electromagnetic wave, possess both volatile characteristic including wave propagation as well as matter particles. Here three fundamental wave propagations, such as micro-diffraction, reflection as well as absorption, have been acknowledged. To effectively undergo the intended experiment, the wavelength 3cm of frequency
Item no.: F21 Introduction The electromagnetic waves consisting of most common light source, such as Sun or laser ray might have its oscillation in different plane by turn as it travel toward specified direction (unpolarized light). Of course, we also might use a polarizer to change the mean distribution of light energy i.e., the intended
Item no.: F10 Introduction As we know, optics is very influential in everyday lives i.e., various colorful objects, from the moment we open our eyes in the morning, will be captured promptly. Maybe that is primarily attributed to different wavelengths of lights, reflected off objects, irradiated into eyes. Base on it, camera works might be carried
Item no.: F09 Introduction To survey fundamental thermodynamics, experiment kit of thermal engine, build-in-piston and gas cylinder, is developed to investigate the relationship among gas pressure, volume and temperature. Here the essential experiments including Boyle’s law, Charles, Gay-Lussac’s law, combined gas law, as well as Carnot cycle will be performed in this subject. Through thermal
