Hi, need to submit a 4000 words essay on the topic ''How does the distance from the radius affect the frequency of its sound''.

Sound, like all other waves display various properties. These properties include wavelength, period, frequency,speed, amplitude, intensity and direction. Amplitude and loudness refer to a similar thing. It depends on how much compression is done. Sound waves disperse after leaving the source. This leads to a notable decrease in amplitude. In case of an absorption of the sound waves by the medium, amplitude decreases as it travels through it.

Sound wavelength is the distance from one crest to the next. Sound being a compression wave has its wavelength being the distance between the maximum compressions. Sound frequency refers to the passing rate of waves at a given point. It is used interchangeably with pitch and also note for musical sounds.

But for all wavelengths, sound's velocity is roughly the same. Therefore frequency comes in handy in the description of the effects of the various wavelengths. Frequency and wavelength determine the pitch of a sound wave. A high pitched sound is in corresopondence with a high frequency sound wave and vice versa for low pitched sounds.

Under normal circumstances, one effect can observe the Doppler Effect any time the source's velocity moves slower than the wave's velocity. However, whenever the source's velocity is the same or faster than the wave's speed, the source becomes the leads the waves produced. When there is a time snapshot for various waves an aeroplane produces with due to moving at the same velocity as the wave, it is called a shorkwave. This also happens if the plane is swifter than the sound's speed.

When a supersonic aeroplane passes an obeject, a sonic boom is heard. It happens due to a pile-up of compressional fronts on wave pattern's conical edges. This piling up interferes with one another, producing extremely high pressure zones. These zones then all reach the object at once. There follows rarefaction where the high pressure zone is immeidately followed by lower pressure one, creating loud noise.

Sound speed is mainly dependent on the medium the wavesare travelling through. This is normally the material's fundamental property. Physical properties including a sound's velocity vary depending on the environmental conditions. For instance, the velocity of soundwaves in though gases is highly dependent on the temperature. The vibration of a sound source creates compression waves of sound.

In order to study the effect of distance from the midpoint of a snare on the frequency emmitted, the Doppler Effect theory is employed. According to this theory, there is always a change in frequency and wavelength of sound waves and other waves in general with respect to distance. It derives its name from Christian Doppler, an Austrian physicist and mathematician. He first proposed this effect in the year 1842 in his book. Later in 1845, Buys Ballot tested this hypothesis for sound waves.
