What are the opposite words for redshift?

Redshift is a term used in astronomy to describe the shift in wavelength of light emitted by an object moving away from the observer. Antonyms for redshift would be blueshift, which refers to the increase in wavelength of light emitted by an object moving towards the observer. Another antonym for redshift is the term stagnant, which refers to the absence of any motion or movement of an object. When an object is stagnant in space, its light does not show any shift in wavelength, and hence, there is no redshift or blueshift. In short, while redshift refers to an increase in wavelength, blueshift denotes a decrease, and stagnant means no shift at all.

One antonym for the term "focus groups" is "individual interviews." While focus groups involve a group of people discussing a particular topic, individual interviews involve a one-...
