When will a scientist observe the redshift in the spectrum of a distant space object? when the object is in the same reference frame as the scientist
when the object is heading towards the scientist
when the object moves away from the scientist
when the object is stationary
HELP ME PLEASE!!! Quick check of redshift and blueshift (Connexus)
(1) What situations could cause two observers (A and B) to measure different frequencies for the same vibrating object? Choose the two correct answers.
– Observers A and B move at different speeds relative to each other
– Observer A is stationary and Observer B is moving.
(2) When will a scientist observe the redshift in the spectrum of a distant space object?
-When the object moves away from the scientist
(3) Why do scientists observe blueshift in some stars?
-Frequencies of light waves increase as an object moves towards the viewer
YW XD Alright! So @A+Student was actually right (I didn’t want to follow theirs immediately because a lot of people said they were wrong and it made me anxious.)

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. The frequencies of light waves increase as an object moves towards the observer. thank you so much a student + you were 100% correct these answers are all wrong btw don’t listen i got 0/4
you won’t pass if you listen to it The look is wrong Thank you A+ Student ♥ 100% correct 26/04/2022 Dear lord-
Do you realize that the order of the answers changes for everyone? /genq /lh
(I’ll try the quick check myself and put in the correct answers when done!) Student A+ I got well except the last 1. B
2.C,D
3.B
100%
Hope this helps 1.B
2.A,D
3.A
I hope this helps you!!
Everything is fine (:B
B,D
A abcdefghijklmnopqrstuvwxyz What the hell is that good for? Anyway, I did the quick check and here are the answers. Have a good day, unless you’re a terrible person, then never have a good day.
1: A and C
2: One
3: One
