Nov 5, 2025 · Sound travels in waves that are disturbances that move through a medium by causing particles to vibrate back and forth.

6 days ago · The study of sound should begin with the properties of sound waves. There are two basic types of wave, transverse and longitudinal, differentiated by the way in which the wave is propagated.

There are two ways radio stations modulate their carrier waves: amplitude modulation, or AM, and frequency modulation, FM. AM radio broadcasts a carrier wave that maintains a constant frequency, …

Dec 12, 2025 · Electromagnetic radiation - Radio Waves, Frequency, Wavelength: Radio waves are used for wireless transmission of sound messages, or information, for communication, as well as for …

6 days ago · Sound - Decibel, Frequency, Amplitude: The ear mechanism is able to respond to both very small and very large pressure waves by virtue of being nonlinear; that is, it responds much more …

Nov 20, 2025 · Mechanical waves, such as sound, require a medium through which to travel, while electromagnetic waves (see electromagnetic radiation) do not require a medium and can be …

sound, Mechanical disturbance that propagates as a longitudinal wave through a solid, liquid, or gas.

6 days ago · Sound - Frequency, Wavelength, Absorption: In addition to the geometric decrease in intensity caused by the inverse square law, a small part of a sound wave is lost to the air or other …

6 days ago · Sound - Standing Waves, Frequency, Wavelength: This section focuses on waves in bounded mediums—in particular, standing waves in such systems as stretched strings, air columns, …

A digital system samples a sound’s wave form, or value, several thousand times a second and assigns numerical values in the form of binary digits to its amplitude at any given instant.
