Description : The device used for measuring the wavelength of X-rays is – (1) G.M. Counter (2) Cyclotron (3) Bragg Spectrometer (4) Mass Spectrometer
Last Answer : (3) Bragg Spectrometer Explanation: Bragg Spectrometer is an instrument used to analyze crystal structure by using X-rays. In it, a beam of collimated X-rays strikes the crystal, and a detector measures the angles and intensities of the reflected beam.
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.
Description : Which one of the following instruments is used to study dispersion of light? (1) Microscope (2) Telescope (3) Spectrometer (4) Photometer
Last Answer : (3) Spectrometer Explanation: Dispersion occurs when different frequencies of light have different phase velocities, due either to material properties (material dispersion) or to the geometry ... portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials.
