The Doppler effect is a natural phenomenon we experience in our everyday life. The phenomenon is even found useful in different situations.  We use the Doppler effect to detect an approaching bus or a train. In the hide and seek game, we perceive the sound of our opponent because of the Doppler Effect.  But what […]

Introduction Young successfully carried out an experiment to determine the wavelength of light in 1801. Young’s problem was that the normal light sources of the day (candles, lanterns, etc.) couldn’t be used as coherent light sources. Young’s solution involves letting sunlight into the room through a pinhole in a window shutter. The pinhole beam was

What is the Doppler effect? When an object is moving with respect to the observer, then a phenomenon is observed, which is known as the Doppler effect. A typical example of the Doppler effect is when an ambulance comes closer to you from the back, and the siren is on. You will observe an increase

The Doppler effect is a fascinating phenomenon observed in the propagation of waves. It deals with the apparent distortion that happens in the propagation of waves when the source or the observer of the wave are in relative motion.  According to the Doppler effect, the frequency of a wave undergoes an apparent change when it

The Doppler Effect in sound was named after Austrian physicist Christian Doppler, who was the first to describe this phenomenon in 1842.  An overall experience regarding the Doppler Effect is the pitch change heard when a vehicle or a sound approaches the observer.  We all have witnessed or observed the effect sometime or the other

Doppler effect also termed as Doppler shift is a phenomenon which is observed whenever the source of waves is moved with respect to an observer. When an ambulance crosses you with its siren blaring is a common example of the Doppler Effect. Doppler Effect Explanation The Doppler effect is a very important phenomenon in various

The Doppler effect is described by the change that happens in the frequency of a wave which is corresponding to an observer who is moving relative to the wave source. Another name of the Doppler effect is the Doppler shift. An Australian physicist Christian Doppler stated the Doppler principle in the year 1842, after his

The demodulation process is the method of extracting the original signal, which carries the information, from the carrier wave. An electronic unit called the demodulator is used to extract the information from the modulated wave. Since demodulation is the extraction of information, the output from a demodulator could be video signals or simply digital signals

The Nyquist rate, often known as frequency, is the smallest rate at which a finite bandwidth signal must be sampled in order to retain all of its information. The signal’s sampling rate is kept higher than the Nyquist rate in the differential pulse code modulation procedure to acquire a comparatively better sampling rate. When the

If you wish to learn about the most important and scoring topics of physics, Doppler’s effect is the one. People find it difficult to understand the theory of this subject. But trust me, your concepts will be crystal clear after reading this article once. The Doppler effect finds its applications in many places, which will
