Introduction: The method of modifying the carrier signal in response to the message signal is known as modulation. In the process of modulation, the high-frequency sine wave signal is referred to as the carrier signal. The modulating signal is the name given to the output signal. Modulation is a signal processing technique that involves shifting […]

Class 11, Doppler effect, IIT JEE, Physics, WavesWe generally discriminate between sound and noise in our daily lives. In a nutshell, agreeable consecutive impressions are referred to as sound, whereas disordered or obstructive noises are referred to as noise. Among both sound and noise, there is a thin line. A sound-absorbing substance is useful for lowering noise. Acoustics will be studied in
Introduction One of the important phenomena in our daily life is light Scattering. This occurrence, like the blue color of the sky, the reddish appearance of the sun at sunrise and sunset, the color of the rainbow, and so on, has been observed by everyone since childhood. Light Scattering differs from light reflection and refraction

Class 11, Doppler effect, NEET, Physics, WavesThe Doppler effect is an essential concept for studying sound waves and frequencies. It is applicable in several scientific disciplines such as aeronautics, planetary science, and similar subjects. Christian Johann Doppler first introduced it in 1842. Before understanding the application of the Doppler Effect, let us first go through the fundamentals of the Doppler Effect.

Class 11, Doppler effect, NEET, Physics, WavesWe all feel quite calm when we go near a water body in the evening and enjoy the cool wind blowing near the water body. On the other hand, we feel cooler by putting our feet in the water rather than standing barefoot on the ground if we go near a water body during the

Class 11, Doppler effect, NEET, Physics, WavesThe study of waves is an important part of the physics syllabus. There can be two types of waves – electromagnetic and matter waves, with the frequency of waves defining their nature. Doppler’s Effect was devised by the Austrian physicist named Christian Doppler. Let us understand Doppler’s Effect, its brief history, and its formula. We

Class 11, Doppler effect, NEET, Physics, WavesDoppler effect also known as doppler shift is a phenomenon which is observed whenever the source of waves is moving 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 different
What is diffraction? Diffraction is the spreading of waves in the presence of obstacles. It occurs with sound and electromagnetic radiation, such as light, X-rays, and gamma rays. Light diffraction is when light bends around corners, causing it to roll out and brighten places where a shadow is expected. The silver line seen in the
When white light falls on the prism surface, light is separated from all its colours. A prism is a special crystal formation. Like the force of the ocean, the light energy travels in waves, too. Blue light waves are shorter than red light waves therefore they scatter the most And as the red light waves

Class 11, Doppler effect, NEET, Physics, WavesWe hear multiple sounds daily. Whether it is a tuning fork or the melody of a piano, different sounds are created by the interference of two sound waves. The waves thus created by superimposition have different frequencies and alternating softness and loudness. Such fluctuations are beats that are of great interest in physics. What are
