When will a scientist observe redshift in the spectrum of a distant space object?
when the object is in the same frame of reference as the scientist
when the object is moving toward the scientist
when the object is moving away from the scientist
when the object is stationary

Redshift and Blueshift Quick Check (Connexus)
(1) Which situations might cause two observers (A and B) to measure different frequencies for the same vibrating object? Select the two correct answers.
-Observer A and B are moving at different speeds relative to each other
-Observer A is stationary and observer B is moving.
(2) When will a scientist observe redshift in the spectrum of a distant space object?
-When the object is moving away from the scientist
(3) Why do scientists observe blueshift in certain stars?
-Light wave frequencies increase as an object moves toward the observer

Dear lord-
Do you guys realize that answer order changes for everyone? /genq /lh
(I'll try the Quick Check myself, and put the proper answers when done!)

Ok! So @A+ Student was actually right(I didn't want to go with theirs immediately, since a good few people said they were wrong and it made me anxious.)
Correct for "Redshift and Blueshift Quick Check" as of 9/15/2022
When will a scientist observe redshift in the spectrum of a distant space object?
C. when the object is moving away from the scientist.
Which situations might cause two observers (A and B) to measure different frequencies for the same vibrating object?
A. Observer A and Observer B are moving at different speeds relative to each other.
D. Observer A is stationary and Observer B is moving.
Why do scientists observe blueshift in certain stars?
D. Light wave frequencies increase as an object moves toward the observer.

1. When the object is moving away from the scientist.
2. Observer A and Observer B are moving at different speeds relative to each other. & Observer A is stationary and Observer B is moving.
3. Light wave frequencies increase as an object moves toward the observer
