A red-shift in the light from a star shows that the distance between us and the star is increasing. The bigger the red-shift the faster the star is moving away.
Student: "Teacher what is red shift?"
Teacher: "Red shift is the wavelength of the light that is stretched, so the light is seen as 'shifted' towards the red part of the spectrum. "
