In the E-M spectrum, it is called a frequency meter.
An oscilloscope is commonly used to measure frequency by displaying the waveform of the signal and showing the number of cycles per second. Other instruments like frequency counters or spectrum analyzers can also be used to measure frequency accurately.
A graduated cylinder or a measuring cup is typically used for measuring liquids. These instruments have marked increments to help accurately measure volumes of liquid.
When you count the number of waves per second, you are measuring the frequency of the wave. The unit used to measure frequency is hertz (Hz).
A graduated cylinder or a syringe can be used to measure 10 ml of water accurately. Alternatively, a measuring spoon that is calibrated for milliliters can also be used for measuring small volumes of liquids.
An instrument is a device used for measuring or monitoring a particular quantity or level, while a gauge specifically refers to a device used for measuring pressure or depth. In general, an instrument has a broader application, encompassing various types of measurement devices, while a gauge is more specialized in its use.
An oscilloscope is commonly used to measure frequency by displaying the waveform of the signal and showing the number of cycles per second. Other instruments like frequency counters or spectrum analyzers can also be used to measure frequency accurately.
Force meter is the instrument used in measuring force.
Weston frequency meter is a type of electromechanical instrument used for measuring the frequency of an alternating current (AC) power system. It typically consists of a moving-coil meter mechanism that reacts to the frequency of the AC signal to provide a reading on its scale. Weston frequency meters are used in various applications to monitor and analyze the frequency of electrical systems.
An instrument used for measuring a quantity of something is called a measuring device or a measuring instrument. Examples include a scale for measuring weight, a ruler for measuring length, or a thermometer for measuring temperature.
