Question

name:
record the definitions for redshift and blueshift in your own words. record an example image to help you remember the differences between redshift and blueshift.

	definition:	movement: (towards or away from earth)	image: (draw a diagram with earth, a star, and waves)
blue shift

Explanation:

Redshift occurs when an object moves away from Earth, stretching light - waves to longer wavelengths (towards the red end of the spectrum). Blueshift happens when an object moves towards Earth, compressing light - waves to shorter wavelengths (towards the blue end of the spectrum).

Answer:

	Definition	Movement (Towards or Away from Earth)	Image (Draw a diagram with Earth, a Star, and Waves)
Blue Shift	The shift of light towards shorter wavelengths due to the source moving closer	Towards	Draw a star moving towards Earth with compressed light waves
