Description : Instrument used to study the behaviour of a vibrating siring is : (1) Barometer (2) Hydrometer (3) (2) Hygrometer (4) (4) Sonometer
Last Answer : (4) Sonometer Explanation: A Sonometer is a device for demonstrating the relationship between the frequency of the sound produced by a plucked string, and the tension, length and mass per unit ... usually called Mersenne's laws after Marin Mersenne (1588-1648), who investigated and codified them.
Description : The waveform of a certain signal can be studied by – (1) Spectrometer (2) Cathode ray oscilloscope (3) p - n junction diode (4) Sonometer
Last Answer : (4) Sonometer Explanation: A spectrometer is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. Cathode ray oscilloscope is an electronic display ... electron beam that is used to produce visible patterns or graphs on a phosphorescent screen.
