Doppler Effect The  Doppler effect  (or  Doppler shift), named after Austrian  physicist  Christian Doppler  who proposed it in 1842, is the change in  frequency  of a  wave  for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a  siren  or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession. If the source moving away from the observer is emitting waves through a medium with an actual frequency  f0, then an observer stationary relative to the medium detects waves with a frequency  f  given by where  vs  is positive if the source is moving away from the observer, and negative if the source is moving towards the observer. A similar analysis for a moving  observer  and a stationary source yields the observed frequency (the receivers velocity being represented asvr): here the similar convention applies:  vr  is positive if the observer is moving towards the source, and negative if the observer is moving away from the source. These can be generalized into a single equation with both the source and receiver moving. With a relatively slow moving source,  vs,r  is small in comparison to  v  and the equation approximates to where  . However the limitations mentioned above still apply. Don’t waste time! Our writers will create an original "Doppler Effect" essay for you Create order When the more complicated exact equation is derived without using any approximations (just assuming that source, receiver, and wave or signal are moving linearly relatively to each other) several interesting and perhaps surprising results are found. For example, as Lord Rayleigh noted in his classic book on sound, by properly moving it would be possible to hear a symphony being played backwards. This is the so-called time reversal effect of the Doppler effect. Other interesting conclusions are that the Doppler effect is ime-dependent in general (thus we need to know not only the source and receivers velocities, but also their positions at a given time), and in some circumstances it is possible to receive two signals or waves from a source, or no signal at all. In addition there are more possibilities than just the receiver approaching the signal and the receiver receding from the signal. All these additional complications are derived for the classical, i. e. , non-relativistic, Doppl er effect, but hold for the  relativistic Doppler effect  as well as.

The management has many roles to play apart from managing people and business. Its role is to efficiently expand the business and try solving the problems that the country or the organization faces. The management and executives should not be greatly affected by the environment and surroundings that it works in. The role of the manager is to efficiently do all the work using its managerial skills (Mujtaba 2013). The author agrees to the thesis statement of the article.
