SYNTHESIS EXPERIMENTAL INSTRUMENT FOR MEASURING SOUND VELOCITY Manufacturer,and suppliers in China,
To measure propagation velocity of supersonic wave has important significance in application of supersonic wave to such measurements as distance finding, positioning, flow rate of liquid, modulus elasticity of material and transient change of gas temperature. The sound velocity laboratory apparatus produced by our corporation is a multifunctional one, which can not only be used for observing standing wave and phenomenon of resonance interference to measure propagation velocity of sound in the air, but also observing double slits interference and single slit diffraction to measure the wavelength of sound wave in the air, as well as observing the interference of initial wave and reflected wave. Through the experiment, the students will master the basic principle and test method of wavemotions thorough. The apparatus has following advantages:
1. Adopted with minitype high efficiency ultrasonic sensor. The sensor is shielded with metal case, possessed of strong antijamming capability and perfect acknowledgement signal;
2. Connection of ultrasonic receiver and rotating device can make the angle of rotation being read out; with the proper double-slit and single-slit sheets, the experiments of double slits interference and single slit diffraction can done.
3. Equipped with reflector plate, the apparatus can fulfill the interference experiment of initial wave and reflected wave when the reflector and receiver are at a certain angle, and display wave node diagram as well.
EXPERIMENTS:
1. Learn the generation and receive principled of supersonic wave; how to measure the propagation velocity of sound in the air by way of phase method and resonance interference; and make comparison with the recognized value.
2. Study interference figure formed by reflected wave and initial wave, namely realization and anacom of Lloyds mirror interference experiment;
3. Observe and measure double slits interference and single slit diffraction of sound wave and make comparison with the theoretical value.
