    Ripple Tank with Projection Screen

    €51.30
    Description: The demonstration device "Wave bath" is designed for modeling vibrational and wave motions on the plane during demonstration experiments on the theme "Mechanical oscillations and waves". The multivibrator included in the device allows creating natural surface waves on a water mirror. Using the built-in stroboscope, students can observe an instant picture of their distribution. The composition of the device: wave bath with built-in screen illuminator wave source with a set of nozzles obstacle set methodological materials Experiment List Circular wave demonstration Demonstration of plane waves Reflection of a plane wave Reflection of a circular wave The Huygens principle Secondary waves from a plane wave Secondary waves from a concentric wave Interference of two circular waves A necessary condition for interference Interference in a reflected wave Interference in a plane wave Standing Waves Standing wave in a corner reflector Diffraction of a wave by an obstacle Diffraction of a wave by a slit Diffraction on two slits Definition of wavelength Determination of wave propagation velocity Product Weight: 14.76 kg Volume: 0.065

    Sine wave generator

    €0.00
    It is to generate sine wave,gives total frequency range 0.5 to 999.9Hz, dimensions 90x90x100 mm, 15W

    Audio Generator

    €0.00
    Our device is capable of generating between 0.1Hz and 100 kHz. Unlike normal sounds, it can generate square as well as sine waves. Square waves are signals that instantaneously shift between two separate levels. For convenience, it has six levels. A knob located in the upper right corner precisely controls the frequency. There is also a jack for a 5.5-watt speaker, which is controlled by a dedicated amplitude knob. The entire unit runs on 110 V AC. An included cord allows you to plug the device into a wall outlet.

    Vibration Generator

    €0.00
    Provides mechanical oscillations when given input signals from oscillator or AF oscillator. A specially designed coil system enables the unit to be operated at its maximum rating for a prolonged period without any damage due to overheating. The frequency response encompasses the whole of the audio spectrum and beyond. Electrical input via a pair of 4mm shielded sockets and oscillating mechanical output is available through a shaft at the top. A locking arrangement provides safety to the apparatus during storage or transportation by blocking the motion of shaft.
