Doppler Effect is a concept developed by Christian Doppler who after a physical experiment discovered how changes in the wavelength, velocity, and frequency affects the transmission of waves and thereby transmitting of the sound detectable by the human ear. Ganguly (2009) defines the Doppler Effect as the change in the frequency of the sound reflected by a moving object such as release ambulance or a moving vehicle or airplane that produces and transmits sounds. It should however be noted that it is only the waves of the sound that are transmitted thereby causing the sound we hear. Using the Doppler Effect this paper establishes this relationship (Ganguly, 2009).
Change the velocity ratio to zero
When the velocity ratio is changed to zero with the frequency maintained at 3, the wavelength of the You sound waves emitted are uniformity distributed from the source. The wavelength in such a case is equal and uniform all round the transmitting object (Surendranath.org).
Change the velocity ratio to values between 0.1 and 0.9
As the velocity ratio increases from 0.1 to 0.9, there is a change in the wavelength in front of the transmitting body and behind it. At this increase in the velocity rate, the wavelength keeps on increasing behind the body and decreasing in cheap nba jerseys front of the body. This means that (2016) the sound is almost transmitted equally to the body towards the direction but far from it behind it. It leaves so much noise behind than the one it wholesale NFL jerseys sends forth (Surendranath.org).
Change the velocity ratio to values between 1.1 and 2.0
When the velocity is above 1.0 that is from 1.1 onwards to 2.0, the wavelength of the sound waves in front of the body becomes extremely small that the body goes ahead of the waves while behind the body the wavelength of wholesale MLB jerseys the sound waves become extremely big transmitting a lot of sound backwards. When the velocity trends is below 1.0, there is almost a uniform distribution of sound waves with the same wavelengths all round the emitting object. However, when the velocity is above 1.0 wavelengths approaching are extremely small that the transmitting body goes beyond the wave’s thereby transmitting sound backwards and not forward (Surendranath.org).
