Doppler effect is an important phenomenon of waves used in medicine, astronomy, weather forecasting etc. In this app, you can have a look at the wave pattern emitted by a source of waves at rest. Understand how this pattern changes due to motion of the source relative to the observer and gives rise to Doppler effect.
This app deals with Doppler effect, a phenomenon that was first studied by an Austrian scientist, Christian Doppler.
The rich and stunning visuals enable the learner to understand with ease the fact that sound propagates in a medium in the form of spherical wavefronts with the source as the centre. A careful elucidation of wave pattern and explanation of certain terms related to waves like wavelength, frequency, and pitch pave the way for a sound understanding of Doppler effect.
Using real world example of a moving train and a car, the app answers the question why and how a wave pattern gets distorted. Its engaging visuals throw light on the fact that it is the motion of the source relative to the observer which is responsible for the waves ahead of the source to be squashed and those behind to be spread apart.
Moreover, there is a quiz provided to test your knowledge of the topic. The key terms, images, and related web links are some other learning tools in the app that will help you consolidate your knowledge on Doppler effect considerably.
