Objective : To Study of Lissajous Patterns Apparatus has been designed to study the various Lissajous figures when sine wave signals of same frequency differs in phase.
Features : Fixed Output DC Regulated Power Supply of +15V. Builtin Sine Wave Oscillator of 1 kHz frequency. Capacitor & resistance are mounted behind the front panel selectable through SPDT switches with connections brought out on sockets. One potentiometer (S) is mounted on the front panel to change the phase difference. One operational amplifier IC 741 is placed inside the cabinet with connections brought out on sockets for 180°Phase Shift
Michelson Interferometer can be used with He-Ne laser or sodium lamp unit
Objective : Stefan’s Constant apparatus has been designed to study the Stefan’s law of radiation.
Features : Continuously variable, over load & short circuit protected DC regulated power supply of 0 to 20V. Voltmeter & Current meter are mounted on the front panel to measure the voltage & current. Bulb holder with bulbs 19 Volt is mounted on the front panel
It is simple & direct device to determine the ultrasonic velocity in liquid with a high degree of accuracy. The ultrasonic interferometer consists of the following parts.
1) The high frequency generator (2MHz).
2) Measuring cell (2MHz) (LC=0.01mm)
