29 Νοε 2016 · The document discusses the Doppler effect, which is the change in frequency of a wave for an observer moving relative to its source. It explains that the observer perceives an upward shift in frequency when the source approaches and a downward shift when the source retreats.
1 Μαρ 2015 · This document discusses the Doppler effect, which is the change in frequency of a wave due to the motion of the source or observer. It defines the true frequency, apparent frequency, velocities of the source and observer, and true and apparent wavelengths.
2 Μαρ 2015 · This shift in frequency due to motion is known as the Doppler Effect and applies to sound waves, light waves, and other wave phenomena. The document discusses the Doppler effect, which is the change in frequency of a wave for an observer moving relative to its source.

17 Νοε 2014 · The Doppler Effect is the motion induced change in the observed frequency of a wave. The effect can only be observed/seen due to the relative motion between the observer and the wave source. 297 views • 11 slides
Class 10 Physics notes according to FBISE syllabus. Contains solved exercises, review questions, MCQs, important board questions and chapter overview.
The Doppler effect describes how the observed frequency of waves is changed by the relative motion between the source of the waves and the observer. When a source approaches an observer, the observer encounters waves with a higher frequency.
