No, MRI (Magnetic Resonance Imaging) does not use sound waves; it relies on strong magnetic fields and radiofrequency pulses. The magnetic field aligns hydrogen atoms in the body, and the radiofrequency pulses disturb this alignment. When the pulses are turned off, the hydrogen atoms emit signals as they return to their original state, and these signals are then converted into images by the MRI machine.
Ultrasound imaging, also known as sonography, is the diagnostic technique that creates images of deep body structures by recording the echoes of pulses of sound waves above the range of human hearing.
Coils of copper wire are wrapped around the magnets. The music in your radio is converted to electrical pulses that move thru those copper wires wrapped around those magnets. The direction and strength of those electrical pulses causes them to have a magnetic reaction with the flowing electricity. This magnetic reaction is connected to a moving mechanism that is attached to your speaker cone. The way the cone moves back and forth from this coil reacting to the magnet recreates the sound coming from the radio station So the magnet is just to turn your speaker into a big electromagnet that moves like a solenoid in response to changing electrical impulses that duplicate the sound generated. The magnet has a constant field, but the coil of wire is the electromagnet but it reacts to permanent magnet. Usually the bigger the permanent magnet the bigger the sound the speaker can produce because it can generate stronger pulses from that solenoid coil that reacts to the magnet under electrical impulses
The imaging technique you are referring to is likely ultrasound imaging. Ultrasound uses high-frequency sound waves to create images of organs and structures inside the body. It is commonly used in medical diagnostics for its ability to provide real-time images without exposing the patient to harmful radiation.
The part of the eye that directs nerve pulses to the brain is the retina. The retina contains photoreceptor cells, known as rods and cones, which convert light into electrical signals. These signals are then transmitted through the optic nerve to the brain, where they are processed into visual images.
The Megellan space craft that mapped the surface of planet Venus used microwave pulses. This type of electromagnetic radiation has a long wavelength (compared to visible light) that is able to pass through the thick carbon dioxide clouds on Venus. the reflections of these pulses were then used to build up a picture of the solid surface beneath.
The pulses differ because the two pulses are in opposite directions.
There is a magnet in the both the microphone and speaker. They change differences in air-pressure (in the microphone) to electrical pulses, and in the speaker, they cause the cone to vibrate - creating sound.
A series of evenly timed pulses create a wave with a constant frequency, also known as a periodic wave. The repetition rate of the pulses determines the wave's frequency, while the amplitude of the pulses determines the wave's intensity or strength. This type of wave can be observed in various phenomena such as sound waves or electromagnetic waves.

A series of evenly timed pulses create a waveform known as a square wave, which has a sudden transition between high and low states. This waveform is commonly used in digital electronics for encoding binary signals.
A periodic wave.

200 tonnes. the electro magnetic pulses create a zero space weight to which is impossible to feel.
Yes, there is carbohydrate in pulses. .
