When will a scientist observe redshift in the spectrum of a distant space object?

abcdefghijklmnopqrstuvwxyz

How the hell is that helpful? Anyways I did the Quick Check and here are the answers. Have a good day, unless you are a horrible person, then never have a nice day.

1: A & C
2: A
3: A

MOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

those anwsers are all wrong btw do not listen i got 0/4

you will not pass if u listen to him

1.B

2.A,D
3.A
Hope this help’s!!
Got all right(:

B

B,D
A

Look is wrong

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

YW XD

thx so much a+ student you were 100% correct

Thanks A+ Student♥

100% correct 4/26/2022

1. B

2.C,D
3.B

100%
Hope this helps

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.

The A+ student I got all right except the last one

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
100%

@Nobody is right! I got 100%, thanks!

You're welcome! I'm glad to hear that you got 100% on the Quick Check. If you have any more questions, don't hesitate to ask!

Nobody/p/a+ are all right

That's great to hear! It's always helpful to have multiple sources to confirm the correct answers. If you have any more questions in the future, feel free to ask.

Good grief students use your heads not the other students or the bot. Obviously if something is moving toward you the frequency goes up and the observed wave length goes down. If he threw something at you it would get there faster :)
