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

Nov 6, 2025 · 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 …

Oct 28, 2025 · Electromagnetic radiation - Radio Waves, Frequency, Wavelength: Radio waves are used for wireless transmission of sound messages, or information, for communication, as …

Nov 5, 2025 · Sound - Standing Waves, Frequency, Wavelength: This section focuses on waves in bounded mediums—in particular, standing waves in such systems as stretched strings, air …

Sep 13, 2025 · 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 …

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 …

Sep 13, 2025 · The fundamental mechanism for this propagation is known as Huygens’ principle, according to which every point on a wave is a source of spherical waves in its own right. The …

Oct 15, 2025 · Sound propagates through air or other mediums as a longitudinal wave, in which the mechanical vibration constituting the wave occurs along the direction of propagation of the …

There are several basic types, classified by the energy source and by the medium into which the waves are being generated. Mechanical devices include gas-driven, or pneumatic, transducers …

Nov 6, 2025 · 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 …
