Doppler Shift Basics
The Doppler shift is a phenomenon that describes the change in frequency of a wave in relation to an observer who is moving relative to the wave source. This effect is commonly observed in the context of sound and light waves, and it has important applications in various fields such as astronomy, weather forecasting, and medicine.
The Doppler shift occurs when there is a relative motion between the wave source and the observer. If the source is moving towards the observer, the waves will be compressed, resulting in an increase in frequency. Conversely, if the source is moving away from the observer, the waves will be stretched, leading to a decrease in frequency.
The amount of frequency shift is directly proportional to the relative velocity between the source and the observer. The relationship between frequency shift, wavelength, and velocity is given by the following equation:
$$f_o = f_s (v \pm v_o) / (v \pm v_s)$$
where:
- $f_o$ is the observed frequency
- $f_s$ is the source frequency
- $v$ is the wave velocity
- $v_o$ is the observer velocity
- $v_s$ is the source velocity
