Doppler effect

Doppler effect Open the browser and type “vlab.amrita.edu” in the address bar. Click ‘Physical Sciences’ and then click ‘Harmonic Motion and Waves Virtual Lab’. Click ‘Doppler Effect’ and Go to “simulator” tab to do the experiment. sign up one time with your e-mail Select medium of travel, detector direction and source direction by clicking the drop down menu. Change relative motion between source and observer by adjusting the velocity of the source and observer using the slider. Discuss how apparent frequency is changes with respect to actual frequency by changing position of source and listener. Also try for different source frequencies. Steps In this activity you will be able to learn how the observed frequencies of a sound changes with the velocities of the source and the observer (Doppler effect).
