A microphone is an instrument that uses electricity to measure sound waves. It converts sound waves into electrical signals that can be amplified, recorded, or processed by electronic equipment.
A seismometer is the instrument used to measure waves, such as seismic waves, within the Earth. This device detects and records the vibrations caused by seismic events like earthquakes. Seismometers are essential tools for studying the structure and properties of the Earth's interior.
A seismograph is an instrument used to measure movement of earthquake. It measures the seismic waves of that area.
A telephone is an instrument that sends voices using electricity. Sound waves are converted into electrical signals, transmitted through wires or wireless networks, and then converted back into sound at the receiving end, allowing people to communicate over long distances in real time.
Earthquakes can vary in intensity to something that is barely felt to a quake that can bring down buildings and cause a major loss of life. The instruments scientists use to measure them is called a seismometer.

Distomat is an instrument used to measure distance using light and radio waves.
A sonar instrument emits sound waves to measure the ocean floor. The sound waves travel through the water and bounce back when they hit the seafloor, allowing the instrument to calculate the depth and map the topography of the ocean floor.
Seismometer (or seismograph) and it measure seismic waves
A seismometer or seismograph will measure the amplitude and frequency of seismic waves which are produced by earthquakes.
A device called a echo sounder or sonar is used to measure the depth of the ocean using sound waves. Sound waves are emitted from the instrument and the time taken for the sound waves to bounce back from the ocean floor is used to calculate the depth.
A seismometer is the instrument used to measure horizontal movements along faults. It records the seismic waves generated by these movements.
Used to measure earthquake activity with sound waves.
