## Redshift to Velocity Formula

The following equation is used to calculate the Redshift to Velocity.

V = Z * C

- Where V is the velocity (m/s)
- Z is the redshift ratio
- C is the speed of the wave (for light this is always a constant 299,792,458 m/s

To calculate the velocity from redshift, multiply the reshift ratio by the speed of light.

## What is a Redshift?

Definition:

Redshift measures the ratio of the speed of an object relative to the speed of light. The redshift describes the rate at which an object is getting closer to the observer.

## How to Calculate Velocity From Redshift?

Example Problem:

The following example outlines the steps and information needed to calculate

First, determine the redshift ratio. In this example, the redshift ratio is found to be 1.5.

Next, determine the speed of the wave. For this problem, the speed of the wave is found to be 100,000,000m/s.

Finally, calculate the velocity from redshift using the formula above:

V = Z * C

V = 1.5 * 100,000,000 m/s

V = 150,000,000 m/s
