The three aspects of sound waves are wavelength, frequency and amplitude. Wavelength describes the distance between each sound wave, and frequency relates to the number of waves counted in a specified amount of time. The energy in a sound wave is called amplitude.
The three aspects can also be seen when looking at a model of sound waves. Each sound wave has a peak and a trough, and wavelengths are the spaces measured between either the troughs or the peaks. Higher frequencies have shorter distances between the troughs or peaks. The amplitude of a sound is shown by the height of the sound wave, with higher waves tending to represent louder sounds. The more waves that occur in a period, the higher the pitch of the sound.Learn More
The human voice ranges from a whisper, 20 decibels, to the loudest shout ever recorded at 121 decibels, which is equivalent to the volume of noise produced by a chainsaw or leaf blower. This record was set by a teacher, Annalisa Flanagan in 2010.Full Answer >
Scientifically speaking, sounds are vibrations that spread as an audible mechanical wave through a medium of air or water. The hearing organs are then stimulated by the vibrations.Full Answer >
Nuclear radiation is the release of energy-bearing rays, waves or particles that occurs when an atom is split. This specific process is called fission, and it can occur in both natural and artificial situations. Nuclear energy can be harnessed from these reactions and transformed into usable electricity, but the waves and particles released during fission can also cause radiation that is dangerous to living beings.Full Answer >
Several characteristics define sound, including frequency, pitch, loudness, wavelength and period. Sound travels in waves and is caused by vibrations. Sound travels fastest through solids, slowest in gases and at an intermediate speed through liquids.Full Answer >
