Input interpretation
Doppler redshift
Equation
z = v/c | z | redshift v | velocity c | speed of light (≈ 2.998×10^8 m/s) (gives the nonrelativistic redshift in the light spectrum of an object moving at velocity v directly away from the observer)
Units
Input value
velocity | 3×10^6 m/s (meters per second)
Results
redshift | 0.01001
Possible intermediate steps
Calculate the redshift using the following information: known variable | | v | velocity | 3×10^6 m/s The relevant equation that relates redshift (z) and velocity (v) is: z = v/c Substitute known variables and constants into the equation: known variable | | v | velocity | 3×10^6 m/s constant | | c | speed of light | 2.99792×10^8 m/s | : z = (3×10^6 m/s)/(2.99792×10^8 m/s) Cancel the units in (3×10^6 m/s)/(2.99792×10^8 m/s): z = (3×10^6)/(2.99792×10^8) Evaluate (3×10^6)/(2.99792×10^8): Answer: | | z = 0.010007
