The 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.  […]

We 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

The 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

Doppler 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
