The Doppler Effect occurs when a source emitting any type of wave (e.g. sound, light) and an observer move towards or away from an observer. For example, light waves emitted from a source moving towards the observer will have shorter wavelengths and are said to have “blueshifted.” Conversely, light waves emitted by a source that is relatively moving away from the observer will be perceived as having longer wavelengths or have “redshifted” (Prather 73; Young and Freedman pp. 533-538).

Question 1

It is said to have blueshifted because of the shifting to shorter wavelengths.
The source emitting the light waves is Continue reading...

The Doppler Effect is a phenomenon that happens when the source of the wave and the observer is moving closer or away from each other. In the case of light, when the source and the observer moves closer to each other, the light as observed will have shorter wavelength (blueshifted) while when the source and the observer moves away from each other, the light as observed will have longer wavelength (redshifted).
In the situations A to D, only situation C experiences a light shifted to a shorter wavelength, hence, the light is blueshifted. This is because the source of Continue reading...
