When an electron loses its partner, it creates a free radical, which is usually unstable and highly reactive. Free radicals typically go through the body to seek out a replacement for their missing electron, and that can result in damage to cells, proteins and DNA. So how do free radicals...
Sound waves are created by object vibrations and producepressure waves, for example, a ringing cellphone. The pressure wave disturbs theparticlesin the surrounding medium, and those particles disturb others next to them, and so on. The pattern of the disturbance creates outward movement in a wave...
Sound waves are longitudinal waves that travel through a fluid. Longitudinal waves are waves where particles of the medium vibrate back and forth in the direction of the wave (unlike transverse waves where particles oscillate up and down perpendicular to the direction of the wave). This particle ...
When the bell flexes away, it pulls in on the surrounding air particles. This creates a drop in pressure, which pulls in more surrounding air particles, creating another drop in pressure, which pulls in particles even farther out. This pressure decrease is calledrarefaction. How Hearing Works ...
There are two types of waves: Longitudinal waves and Transverse waves. Longitudinal Waves:A wave in which the particles of the medium vibrate back and forth in the ‘same direction’ in which the wave is moving. Medium can be solid, liquid or gases. Therefore, sound waves are longitudinal ...
Imagine yourself in a bustling city park or near a flowing river; the collective blend of these sounds creates the environmental noises unique to that setting. Ambient noise is diverse and dynamic, reflecting the character of a specific location. It sets the tone of our surroundings and can hav...
Waves have an amplitude (volume), frequency (pitch), wavelength (speed), etc. The science of sound: how sound waves work In the air, 331 meters per second (MPS) creates something of a "chain reaction," If you watch this closely, you'll notice that the waveforms because an individual ...
The cold air moves down while the warm air moves up, which creates something like friction (摩擦). An electric charge builds up in the clouds. The charge gets stronger and stronger until the explosion(爆炸) happens-and the LIGHTNING flashes.When the lightning flashes, the air around it ...
A spotlight lightsup only one section of a stage; similarly, a “spotsound" creates a circle of sound inone targeted area. This can be useful for businesses. such as restaurants and storesbecause it offers a new way to attract customers. Restaurants can offer a choice ofmusic along with ...
Digital audio recording creates PCM data by measuring an analog (real world) audio signal’s magnitude at regular intervals (the sampling rate) and converting each sample to a numerical value. Standard compact disc (CD) audio uses a sampling rate of 44.1 kHz, with a 16-bit integer describing...
