The wavelength of light coming from a distant galaxy is found to be `0.5%` more than that coming from a source on earth. Calculate the velocity of galaxy.

Explanation

To solve the problem, we need to calculate the velocity of the galaxy based on the change in wavelength of light observed from it. Here’s a step-by-step solution:

### Step 1: Understand the Given Information
We know that the wavelength of light from the distant galaxy is 0.5% more than that from a source on Earth. This means we can express the change in wavelength (Δλ) in terms of the original wavelength (λ).

### Step 2: Calculate the Change in Wavelength
If we denote the original wavelength from Earth as λ, then the change in wavelength (Δλ) can be calculated as:
\[
