Question

explain terms related to sound waves​

Answer 1

Sound is a longitudinal wave which consists of compressions and rarefactions travelling through a medium. Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.

Answer 2

• Sound is a vibration that travels through a transmission medium like a gas, liquid, or solid as an acoustic wave.

• Sound is the receipt of these waves and the brain's perception of them in human physiology and psychology.

• Acoustic waves with frequencies in the audio frequency range (about 20 Hz to 20 kHz) evoke an auditory perception in humans.
• These sound waves have wavelengths ranging from 17 meters (56 feet) to 1.7 millimeters in air at atmospheric pressure (0.67 in).
• Ultrasound is defined as sound waves with a frequency greater than 20 kHz that humans cannot hear.
• Infrasound is defined as sound waves below 20 Hz. The hearing ranges of many animal species differ.
