Though most of the galaxies in the universe are receding from Earth, some are observed to be moving toward us. Suppose a galaxy is moving toward Earth with a speed of 3485 km/s and emits light with a frequency of 4.000 X 1014 Hz. What is the frequency of the light when it reaches Earth?

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
